I'd really love someone to explain this.

[deleted]

Woah, that was awesome. The second attempt kept going so long.

Without a doubt, one of the coolest videos I've clicked on reddit. The engineering behind those rockets is ingenious. I hope someone more knowledgeable about the festival can post more info, and I hope someone more knowledgeable about the physics can post more info on that too.

[deleted]

I think it is actually a two stage rocket. The first stage are rockets on the side of the disc that get it to spin fast like a top. The rocket is still on a pole at this point, so it will be pointed up and if it is well balanced, should be stable.

After the side rockets burn out, a second fuse will light all the vertical rockets on the bottom at the same time. These are the four rockets you see burning in the gif. The gyroscopic force works like you said, and keeps the rocket pointed straight up.

I agree, there definately seems to be a first stage where it spins the wheel for a while to build up the rotational inertia, perhaps just the outer rockets, which have a lower vertical angle of attack, producing more lateral thrust. Or perhaps the inner rockets just have a 30 second delay.

A couple looked quite complex, where they launched, bogged, then re-launched. Or perhaps its just because we have farmer/rocket scientists that it wasn't continuous thrust.

He didn't make them, just observed them.

So wait before Newton invented gravity we weren't just floating around all day long?

No. Before that we were powered by the catholic church. Constant sinning kept up sucked towards hell and prevented us from floating up to heaven.

good explanation but a just to be a little stickler about something. Gyroscopic motion is not responsible for keeping the bike up, you are. sure it might help if you are going really fast and have heavier wheels but at any normal speed it's up to the driver to balance the big using small steering inputs. that's why one must learn to ride a bike. other than that, pretty solid explanation!

Spinning objects have a unique nature due to newton's laws. (or in line with them, not due to them. He didn't make them, just observed them.)

Why must you destroy my childhood fantasy of newton as the great bringer of gravity?

No, seriously, this confused me as a child. I thought people must have been pretty dumb if they didn't discover gravity until newton.

I'm curious if there are angled blades on the assembly so it can get some extra upward motion from the lateral rockets.

The central bar on some of them seems to have propeller shape. Could be seeing things but I wonder if that might help increase the vertical movement.

Bicycles don't stay up due to the rotation of the wheels, they stay up because the rider continuously makes tiny adjustments to the steering to keep the bike underneath themselves. Yes, there will be a small amount of stability from the rotation of the wheels, but it is insignificant.

Yes they do. They wprk together. As do motorcycles. Did you watch the video I hyperlinked?

I'm not so sure. I think the disk has fan blades on it, and the rotation is actually creating lift- more efficiently than straight vertical thrust. But since it can't create lift without atmosphere, it can't be used to launch satellites or space shuttle or anything, that's just a helicopter.

4 sets of motors? I guess that is why you are a pilot not an engineer.

I thought it was a pretty adequate explanation. No one asked for a Bill Nye brain-fuck rundown of all the engineering involved.

Wow, you're not just a troll, you're an asshole.

I am not. I am a full human body!

sorry, engines not motors. And engine is a synonym of motor. So i'm still correct.

But the sound of the announcer is surreal. It's like something out of a Pink Floyd song.

Thai language is tonal and the tones can be exaggerated, especially when there's exciting commentary to give it a little more 'umph' so to speak.

Here's a video of one close up, if that helps

Jesus, no wonder they blow up so spectacularly, the entirety of the fuel is in the tube, with nozzles cut in. That's fucking awesome.

It's similar to a tip-jet helicopter. Rockets are used to spin the blades, then it's the blades which give the craft it's lift, they move a lot more air than the rockets do.
edit: oh, i thought the central beam on these rockets was angled an angled blade like on a helicopter. But it's apparently just a cylindrical bamboo beam with no lifting potential. Oh well.

The engineering lesson behind all of this is that it's more efficient to fly with a lot of cool slow-moving air (ie: propeller), than with a little bit of hot fast-moving air (ie: rocket).
Think of an accelerating car: skidding your wheels on gravel wastes energy. This is like a rocket, skidding on the gravel is like air turbulence, all of the energy that goes into moving that gravel is wasted energy.
What you want to do is grip the ground hard so you can push it away behind you, you want big grippy wheels which push slow-but-sure, a constant calm acceleration, this is what it's like with a slow moving propeller.

(I've got my own crazy aircraft ideas which take this "slow air is the most efficient" principle to the extreme, i'd love to share but i'm a bit paranoid about patent-trolls ruining my life.)

Another way to convert a small mass of fast air into a large mass of slow air is to use the Venturi effect, here's an example: http://youtu.be/aU9ahW6H61s?t=34m50s _(or is it Bernoulli? meh)_.
Aspirators like this are sometimes used in rockets, on pulsejet engines they are called "Thrust Augmenters". I vaguely remember hearing that USSR rockets had an open section partially so that it can suck in air for this purpose, but don't quote me on that. See the open section?.

Does it almost feel like nothing changed at all.

What is this Jimmy Bastille? That sounds like an old gangster name.

The launch at 3:00 was really moving,wish they didnt cut away...

How has no one caught the 2 naked men on a bicycle at 8:06?

What the shit.

Obviously I have too much time on my hands.

the one at 4:15 is pretty cool. First it nearly hits a few people, bounces off the ground, and then reaches a fairly decent height

NASA has a new way to get to the ISS.

And the third one couldn't get it up.

I think the fourth attempt was AMAZING!!

Yeah and the first attempt was like challenger

Third attempt: not so good.

That's what she said.

Those flying discs are so large, too! Initially, I thought they were four feet in diameter or something, but watching the people carry them in... that's got to be at least a 12 to 15 foot span.

The one at the 4:50 mark might go even longer.

The first attempt looked like a tribute to the final Challenger mission.

It's a competition held between neighboring villages in northeast Thailand (and Lao) to see who has the best "bang fai" which is the object fired into the air.

You can read about it more here: http://en.m.wikipedia.org/wiki/Rocket_Festival

Source: my Thai wife told me the name and then I googled it, so I have to give her credit ;)

http://en.m.wikipedia.org/wiki/File:2013_Yasothon_Rocket_Festival_04.jpg

You don't have to give her credit. .... If she wanted credit she'd have her own reddit account. :p

She's got no idea what reddit is...and that's fine with me.

OP and his Thai wife delivered today. I wonder what his other wives know...

/R/askmywives

if you used a lower case r, us lazy folk could just click it!

A) I dont think its an actual sub, and B) why woukd you want theur opinion

It wasn't. .. I just like to see what random subs are about... if they exist

Fair enough, thats why I have /r/hotgirlspooping and /r/sexwithdogs purple

Also, "bang fai" translates to "fire brush/ brush of fire" or "light brush/ brush of light", if I'm not messing up on the transliteration.

Source: Thai- Chinese.

Bang is the bamboo runner used on top of their temples, but you've got the fire right. :)

Ah, ok, I was thinking of 'แปรง' which Google Translate turns into "Pærng"- With a language as tonal as Thai, tons of different words can be transliterated with the exact same Latin characters. At least, that's what I've always encountered.

So Thai Kerbal Space Program basically.

I want one here :(

This seems way cooler than the amateur rocket competitions in the US.

Because they aren't sending people up in them.

Wow, that would give a whole new meaning to "Vomit Comet".

Talk about going to dizzying heights.

Because Coca-Cola is.

Original Red Bull is from Thialand I'm not sure if the knock off version is allowed to compete against the original.

The family that owns Thai Redbull owns 51% of the international version as well. They do promotions in Thailand.

Maybe something to do with blatant disregard for safety procedure

Because forest fires id imagine.

Youtube Link to avoid that site.

What's wrong with that site?

Why can't we have competitions like this in the US? I'd rather watch an hour long show about bamboo rockets than someone in a BBQ competition....

Maybe do it like a biathlon. Rocketry and pit BBQ smoking.

Because...

God as a former EMT that video makes me cringe. First thing they do is lift her head up and then some guy comes out of nowhere and starts administering ghetto CPR. Bleeding out of the ears is definitely not a good sign, but I'm surprised she managed to keep such a firm grip on her phone the whole time.

This has all the right ingredients: rockets, fireworks, danger, party and mayhem. Now if it was at night, that would be spectacular! We got to do this in North America.

How do you win a BBQ competition?

Apparently, a good grill, hand picked wood, whole pigs, and getting up at 3 am to cook....

why wood? you grill with coal, right?

edit: charcoal

Good quality wood from certain types of trees apparently add to the flavor. It think its hickory.

Charcoal yes, you can't use actual coal, it will poison your food.

Yeah that's what I mean \^^

It's not grilling. It's BBQing, or rather, smoking. Different woods impart different flavors to the meat. Mesquite is strong, and a little bitter. Hicktory has a bit of tang to it. I enjoy applewood myself and use it quite frequently.

Charcoal is what you use to grill, but you can also use charcoal to start a fire, and then place wood chips (usually soaked in water to make them slow burn) on it to impart some smoke to meats such as ribs, chicken, and fish which have a faster cook time.

BBQing takes hours because of the low heat, and you use big pieces of meat (like whole shoulders) that are cheap cuts. It takes a long time to penetrate deep with smoke flavor but also to make them soft and tender and delicious.

Today I learned!

thanks for the info

Because it's entirely different. Like charcoal and gas

I think because it looks super dangerous, from a liability standpoint.

Exactly. This is a wonderful example of how much fun you can have when public safety and the threat of death dismemberment and maiming is of no concern. Plus it sort of weeds out the dumb ones..

so what you are saying is that they are more 'murican than anyone else?

Can't we all just get along?

Did you see a bunch of rockets fly off into the wide blue yonder?

There are much cooler amateur rocket launches going on all the time in the USA. You're just too uninterested to look into it.

We do have firework competitions annually, there are organizations for it. Pyrotechnics Guild International hosts some amazing stuff every year and is worth checking out. They even have other events/seminars/guests that cover niche subjects like anvil shooting.

https://www.youtube.com/watch?v=IhQ4dE_RGnQ

Those failed rockets did look a little unsafe. In the US, either lots of people would be sued or everyone would have to be at a safe distance away where you probably wouldn't get a very good view of the rockets.

um... Punkin chunkin?

Well there's Punkin Chunkin, wherein teams of madmen and madwomen build cannons, catapults, trebuchets, and ballistas to hurl pumpkins as far as possible. That might scratch the same things-moving-through-the-air itch as bamboo rockets for you.

So my wife overheard this playing on my phone... Turns out this an event from nearby her hometown in northeast Thailand. She said they have it every year, kind of like a fireworks show.

Do you know what time of year? Id love to go see this in person one day

liability.

Besides I'm sure the greens would complain about pollution. Then of course someones crazy uncle would decided that black powder sucks and attempt a liquid fueled rocket or more modern solid fuel...

Its not exactly difficult or expensive. You're more likely to CATO with a cheap sugar/nitrate or BP than you would more modern fuels that use rubberized binders like in the shuttles solid rocket boosters.

When you do go though it is that much worse.

Thanks for posting the link. That was awesome.

Thanks this is great to watch, although the some of the footage seems to cut too soon!

Fantastic. This video deserves its own post.

Those looks like they where made in garrys mod! Especially the ones which explodes!

This one looked mildly dangerous.

Somebody post a working version, please. This one's font is all screwed up.

That last one went full retard

Thailand can into space?!?

What the fuck was up with the short clip at 8:05 ?!?!

I could swear I recently saw a movie where this competition/festival was a subplot...

what language is the video title written in? its very beautiful

Thai, aka Siamese

The RPM's on that second one in the YouTube video tho!

These look like black powder propelled rockets? If each group made their own engines, that is super impressive!

I like this attempt, personally

The bit beginning at about 6:00 needs to be turned into a downvote gif.

I liked the failures.

Very cool video. Anyone know where I can find more music like that?

Wow that was amazing! I wonder how many injuries occur from stray rockets though.

Edit: Looks like it happens occasionally. https://www.youtube.com/watch?v=iqlXsODSxd8#t=103

First post/video link I see. And it's some thai stuff. Greatttt. 5555

I've never seen or heard of these rockets. I'll def have to ask the folks and see if they've ever witnessed this in action.

I love how dangerous this is, and the lack of safety precautions for both spectators and participants. Almost half of the launches end up exploding or veering off into the crowd. And it's not like the "rocket" is a small thing, it requires several men to carry it.

Looks like the smoke monster from lost

It would be really cool if they could do different colored smoke.

People definitely die doing this.

That was actually really entertaining to watch

The second rocket is nuts. What's up with the guy wearing underwear outside his pants starting at 3:06?

HAHAHA the attempt of minute 4 is hilarious!! everybody running away from a ufo that flies sideways!!

EDIT: minute 6 is the best so far HAHAHA

I love the light it and run procedure.

Clicked first link... Got lost by underboob thumbnail... Thanks!

Jebediah would be so proud!

Sounds like the Transformers transformation sound effect.

and here I am thinking it was just going to plummet back to space and people would just dive out of the way. Parachute's who would of thought.

WHY AREN'T WE FUNDING THIS?

wow those look really dangerous

This is the coolest video I have seen on Youtube in a long time. It looks so dangerous. Especially the one that tips and makes a bee-line directly toward the crowd. I love the thud sound of a gunpowder explosion. I'm gonna step out and watch Thai fireworks for the rest of the night.

this pleases my inner pyromaniac in ways that words can never express.

the failed attempts that resulted in masive crowd-endangering explosions were particularly scintillating.

most excellent.

How did they not burn down the forest?

Reminds me of that scene from the movie Contact!

thailands space program

I would have soiled myself at 4:20

i'm not ashamed to say i watched the whole thing

Wow, this is entertaining. Reminds me of that Mexican hammer-fireworks thing.

the one at 6mins is amazingly funny / scary

Me beginning of video: Why have they all got umbrellas?

Minute into video: Oh that's why..

I can't read those moon runes.

If you watch the video carefully, it shows that it isnt a stick, but a circular something with an X in the middle. The rockets are on one stick, probably angled to help it spin to keep its trajectory.

Pretty cool

I figured it was a circular thingy. I wonder for how long the fuel will last though? It's a pretty interesting contraption.

I guess you need to refill on the moon to get back.

Just leave jeb there and kill multiple kerbals trying to rescue him.

Quick! Someone build this in KSP!

https://imgur.com/a/PNBMi

Quick attempt, didn't get very far but it was decently stable.

here you go, the apoapsis was at 53km.

suprisingly stable, and completely impossible to steer in any direction except up.

I've participated in amateur pyrotechnics for nearly the past decade (making your own fireworks...shells, rockets, fountains, etc). Assuming this is a firework, it would be called a girandola. Its a circular disc with an array of tubes with rocket propellant coming out of nozzles, all with rotational symmetry. Spinning keeps it stabilized during the flight, otherwise it can fly off course and become a hazard.

But to answer your question, duration really just depends on the size of the tubes you wish to use for the device (ie, the amount of propellant, which is usually black powder pressed with a hydraulic press but it can be different depending on the application/desired effect).

Here is a huge girandola that actually explodes (intended to), for anyone interested: https://www.youtube.com/watch?v=0_pgFU7AGKk

Edit- Someone PM'd me asking where to learn more about making fireworks, so I figured I'd share the link here too: http://www.amateurpyro.com/forums/index.php

Still think the best one I ever saw in person was a 14' in 2008 at PGI in Gillete WY was known as the crowdfinder as the direction it went in. Tony makes some great stuff and unfortunately I haven't been able to go for the past several years.

https://www.youtube.com/watch?v=rNQw1LDCHX0

On a small scale they aren't too hard to make, it's when they get big that things get difficult.

Edit: Added some links. Photo source is Dominator Fireworks

Yeah I've been wanting to go the past few years, I've just been way too busy with work. I think its in IN this year (I'm in IL), I may try to go this August. I heard from a friend there are a decent amount of overloads sold in the tents too, so hey, one more reason to go and start to stock up for next year lol. I'm looking to joining HPA in the next year too. Everything I've done/made was by myself, through only reading online sources. I think it would be cool to actually meet other people who share the same interests.

It's a ton of fun and from what I've experienced they tend to be a fairly open group of people willing to teach those who are interested. As long as you are safe and respectful it's fine.

If you've never seen a live show there it's definitely worth it! There are a ton of seminars/workshops you can go to on building stuff too.

Thanks! That clip was super awesome.

Teach me your ways. That thing was awesome

Here is some close-up video of one. I still don't quite see why the thrust is directed downward.

http://youtu.be/JuysJjAw12s

[deleted]

Yes I had expected that there would be rotor-blades, and that this would provide the spin and some lift. Its just cardboard rocket-tubes, running across the diameter. It's unusual for such an arrangement to thrust sideways, relative to the rocket-tubes.

The thrust is angled slightly. They trade some of the upward thrust for the spin yhat stabalizes the craft. You don't need much of an angle to spin the craft because it is so light.

What really threw me on that video was the date--May 9, 2553. Thailand's in the future!

Newton's Third law? How else are you going to make something go up the way?

Sorry that was a brainfart. I mean how it is directed downward. The tubes of the chemical rockets run perpendicular to the direction of travel which is unusual. I guess there are some directional jets, but can't see them.

Ah fair enough. Looks like it's done by those two holes he's tinkering with at the start of the video?

The fuel itself is sideways, but the holes the exhaust needs to escape through are pointing down and slightly sideways.

From the looks of it, it's a tube with holes in it for the exhaust, kinda like some kind of sideways rocket.

Yup, the common term for this type of firework is a girandola. Although I've never seen one as big as those.

Source: My uncle builds a girandola every year for a fireworks competition.

That is awesome.

Can you record it and show us how he makes it?

https://www.youtube.com/watch?v=RT7qEt92-8U

I found the video but the quality isn't so great but there are pictures showing what it looks like. He is slowly stepping it up each year making it bigger / fly higher while trying to keep it stable. If memory serves they are required to make all components themselves. The tubes used for the engines are actually layers and layers of manila folders with a thin layer of glue.

The main crossbar is a metal pipe with holes drilled in it. The pipe is filled with fuel. The other crossbar helps hold the circle of bamboo steady.

I'd really love to see this on Mythbusters. I don't care if there's no actual myth to bust... I just wanna see them build and launch one.

How about this one ? A smaller version : http://youtu.be/JuysJjAw12s
Thanks for /u/intergalactic_camel for the link.

When I saw the video, I thought maybe they were trying out the Wan Hu (Chinese Rocket Man) myth.

Jebadiah Kerman forgot to turn on the RTS and SRS control.

Kerman*

falling to earth at 700mph 

  :D+<

 >+C:

here. You can see the guy tinkering with his. It looks like a straight pipe with two holes for jets. The propellant is stuffed directly inside, which they light. Once enough power comes out, lift is generated. The circular part is made of bamboo and between its ring shape and the jet's opposing, torsional forces, the rocket is stabilized.

The asian space program really took off.

Panda space program

I'll try - think of a Frisbee and how when you throw it, is just magically seems to keep stable and doesn't flip over. This is because the rotation keeps it stable.

Now, take a stick and add rockets to the ends of it, but point them diagonal instead of straight down or straight sideways. Part of the thrust is going to go down and part of it will go sideways, causing the stick to lift and rotate. This rotation keeps it stable.

When you see rocket crashes, they tend to look as if they just fell over and that's because with the thrust on the bottom the rocket becomes heritable unstable. The rotation solves the stability issue. However, this requires more fuel and simply isn't feasible on larger space vehicles.

Also - I want to see this done on Kerbel Space Program.

Thanks! Could you say it's gyroscopic? I'm not sure though, a gyroscope always aligns with something I can't recall anymore.

http://www.youtube.com/watch?v=JuysJjAw12s

This video shows somewhat of what's going on.

Malaysian space program

Manned flights begin on a double dare. Doubles make sense for balancing the load for a spinning vehicle. Once these Spin-naughts have safely parachuted to the ground there is a brief foot race to see who can run in a straight line. Hilarity ensues.

Thanks, what would I do without you...

http://i.minus.com/iWzSTTMLjLXuD.gif

fashion over function...this is a demonstration of an impractical flying object apparently made with unique materials. The jets are anchored such that the object sustains a spin during climb. Knowing that the acceleration due to gravity is constant, I'm not sure whether the prescribed thrust is designed for constant spin or constant velocity climb or neither (because one may think that the apparent equal heights between exhaust plumes imply either). Was probably fun to make though. Also, this is not a helicopter, which is required to have autorotation capability, among a host of other conflicts, not least of which being spin-stabilization.

But it is spin stabilized. If it wasn't spinning it would just flop over and not go straight(ish) up.

It's a clever design in that the spin not only provides gyroscopic stabilization, but also serves to distribute the thrust more evenly over the disk. And it compensates for imprecise thruster construction and pointing.

I'm sure it's not practical in any sense, but it's definitely interesting.

I know it is spin-stabilized, where spin-stabilization is not a property of a helicopter. It is interesting to the uninitiated, which serves an important purpose to attract the attention of the public, but its value must not be overstated when being explained, which was my purpose in reply to a question. I did not simply barge in here hoping to dash dreams.

Also, even thrust distribution over the disk is a consequence of design rather than a feature. Until you realize there is no disk, that this model should not be approximated as an actuator disk, or simple pressure jump across the thrusting plane, because this device propels a thrust at different angles, and such a model would be very inaccurate.

I'm not convinced that the spinning part is purely fashion. Seems to me that in the absence of stabilizing fins, the rotation is necessary for level flight.

I think these contraptions, while impractical, demonstrate a method of attaining relatively predictable flight without having to really engineer anything.

On the other hand, we've come up with an interesting way of making smoke braids.

This really isn't a type of rocket but a spin stabilized disk called a girandola. Its lifted by many rockets and some are angled to provide spin.

Girandolas are not very popular in your typical fireworks show but in amateur pyrotechnics they are a challenging but rewarding firework to make.

The one in your gif is a daytime version that uses smoke to create an effect. Like most daytime fireworks, the night time version is much more exciting. For example here is a two stage one from PGI in 2012.

Large Girandola @ PGI 2012 Competition (Sorry RES users, you have to go to YouTube to view it).

Edit: There are some 1.4G consumer girandolas available. Like Motion Madness by Brothers

Thank you for sharing this. Nice!

I use the same technique so I can attach a babillion boosters to my kerbal space program rocket and still go uppish.

uppish.

They look like they are able to throw up towards the end. That is awesome.

Have you ever thought of rebooting the "undelete" project? With the massive turn of censorship that reddit has seen lately, don't you think the people need it?

Why are they not very popular? They look really cool!

That's a really good question. They require a lot of skill to make from scratch but its probably the same reason why you don't really see rocket based effects in public shows (like a rocket propelled shell).

Maybe its a safety or cost issue, who knows! I think most public shows are kind of cookie cutter anyways. Competitions are really the only place to see creative effects like this.

Dude ! I want this to be a thing where I live. Exciting!

I know! I wish more shows uses effects like this.

Wow, that video was awesome. Thanks for sharing!

If your interested in other types of effects, just search for "PGI" on YouTube. They have a bunch of neat stuff on there.

Why the fuck are those not shot off on the 4th of july??!? Thats the best firework ever.

The pandas are evolving man

To the moon

I never thought there would be a doge-panda partner-ship in getting to the moon. Can I assume the doge is acting as that bank?

"The fucking MOON. I own that. It's mine. Yes I put pandas up there. They said it couldn't be done, and...they were right as it turned out. The pandas exploded." - Dan Halen

This sounds exactly like something Cave Johnson would say.

*Van Halen

Never watched Squidbillies? Dan Halen is a character and this is the episode... or rather part of it. I doubt Van Halen put pandas on the moon.

Yeah, yeah, I thought I'd get points for at least going for some pseudo-cleverness.

All I can offer is an upvote.

Why is the right Panda Austrian? ^.-

Hold my peepee

Just to May every year, the festival was held missiles across northeastern Thailand and Laos, to bring harmony desires weather and bumper crops of farmers. Missiles fly as high, as straight and beautiful smoke trail as the winner

I attended one in Yasathon Thailand. Teams would bring out 20-25 ft rockets and launch them.

Pretty fun. People just partying and shooting fireworks and watching these missile shoot up into the sky. Surprised no one died that day.

Evolution requires breeding.

Tang dynasty can into space.

The new Chinese torture methods are getting more cruel every day. You criticized the government? Bamboo rocket is launched to burrow under your fingertips. Ultimately, these rocket bamboos will be produced commercially, and you'll be able to purchase one way trips to space for your infant daughter.

They've acheived diet coke and mentos technology.

If there are pandas in that rocket, they're very dizzy...

Welp, time to recreate this in Kerbal Space Program...

Looks about right

That went exactly how i thought it would go

here are some less impressive bamboo rockets in video form including a fuck up at the end

This proves that no matter what language you speak, no matter where you call home, there will be rednecks.

They all got lung cancer later that day.

Why is Thor in Thailand?

Just curious how do these work? I understand model rockets but I don't think you can get that kind of engine...or could you? I always loved making rockets when I was younger

Didn't know the "nae nae" was so popular in other countries.

I wonder why there were no women in attendance.

Look, Poland, even Cambodia can into space.

This brought a tear in my eye.

You, Sir, are a genius.

It's a girandola variant.

More like "bamboom rocket." AMIRTIE FELLAS

Puts the North Korea rocket launch to shame.

Moon shoes can do that

I'll have to take your word for it that it's bamboo.

It just looks like a giant version of this

Girandola is what it's called.. and they're awesome. They used to sell a couple smaller, pre-packaged ones in the US, but they were illegal most places, and I'm pretty sure most have been discontinued.

Thanks for the only informative post here!

That's so fucking cool!

How the fuck do you balance something like that?

It is the same principal that makes your bike stay upright. The spinning stabilizes the rocket as it launches. If you watch one of the videos above, you can see that the ones that spin slowly often drift off course or even start flopping around while the ones that spin quickly go in a more straight path

Really though whats the fucking story on this thing?

Brilliant engineering, using the spin to keep it relatively stable.

Double helix all the way across the sky

i see october sky 2 in the works

We need some "fuck this, Im out of here" and "Abandon thread" GIFs to go with this.

Do you like conspiracies? Because that's how you start a conspiracy.

It's good to know Best Korea has been working on their rocket and space technology since their last attempt.

holy shit...now THAT is the coolest thing I've seen all day

And that, boys and girls, is how baby DNA strands are made.

So THAT'S the North Korean missile system we keep hearing about.

How far up did it go?

Looks like the North Koreans are at it again.

wondering where this idea of festivity came from in this culture.....May be it was Ancient Aliens?????

Someone needs to make this in KSP

KSP experience is finally spilling into the real world :-)

How about we raid mythbusters with this thread or video? I would love to see them explaining the science behind these rockets and even improving one of them.

oh god, how is this safe / legal??? 4:08 6:00

Time to send in the troops

That's not a rocket, it is a pyrotechnic girandola. You can find some beautiful examples on youtube, or here (IIRC): https://www.youtube.com/watch?v=wnLz-d_330s&feature=youtu.be

Here is another wonderful sample: https://www.youtube.com/watch?v=wRMNs-qTm3k

A girandola is basically a hoop with rockets attached--at an angle--that make it spin. Many larger girandolas will begin with a one or two "driver rockets" that impart spin but no lift, these will be followed by a multitude of lifting rockets, the spin provides stability. They are easy to build and I encourage everyone here to do so however they are very, very difficult to build well.

What makes this particular one, that /u/CoolAsACucumber shared, extra special is the way the rockets are mounted: they are in a straight line through the center as opposed to mounted on the outside ring. The large amounts of smoke trailing behind is on purpose, the dual helix it forms is the effect, that is why they are launching at daytime. Not all fireworks are pretty lights in the sky. Pyrotechnics is (generally speaking) 3 branched: Light, Smoke, and Noise.

Here are some examples up close:

1 Here is a girandola with a 6" canister shell in the center, the aluminum strip holds a fuse that lights when the rocket in the bottom left corner burns to the end.

2 Here is a massive girandola built on a bamboo frame.

3 Here is a traditional girandola with 6 ball shells attached, they appear to be 3" shells

tl;dr It's not a rocket.

Its been an hour and no one has said "Source??" Mate, you guys are slippin.

I beat my skin flute

I want Mythbusters to make one with Buster on ~~board~~bamboo.

Still waiting for a you tube video on how to do this... anyone?

Mother Nature is preparing for war. She's clearly still pissed about Global warming.

I think I'd need some Dramamine.

Cool as a cucumber

vaguely reminiscent of some of those flying rod things

You heard those were bird and insects motion blurred, right?

Don't know what the fuck I'm looking at but hey it was cool

That's what Snoop would call a "bitch nigga"

That thing look huge compared to the guy (with enormous balls) standing in the foreground.

Awww, I wanted to see it keep going.

So that's where the flying saucers are coming from...

Vilmanas!

Source?

whats that damn annoying this in the bottom left corner after he zooms out? thought something was on my screen

I'm Thai and I didn't even know such a thing existed here!

Bamboo flying saucer.

And now for a sudden sharp rise in UFO sightings in your area

In bamboo we trust.

DNA clouds?

That was pretty cool

I feel lied to...that was a bamboo saucer, totally different

Not a saucer... A hoop. Still, it was rocket-powered.

This must be the new Amazon Prime Panda food delivery service I've been hearing about lately.

Note: I'm not an actual panda.

Theres a movie about something similar. It is placed is Laos though, pretty good movie.

And that's how DNA is made

I'm surprised Mexico hasn't faced more international pressure for test-firing their ICBM stock.

Someone shoulda been riding it

That looks amazing.

That's about the coolest thing I've ever seen!

As it gets higher you can see that it looks exactly like the space station in 2001: A Space Odyssey.

Wut?

Someone's been playing around with Garry's Mod a bit too much

So that's how the Mayans got back to their home planet

/r/oddlysatisfying

For some reason I thought this might have something to do with Anohana.

How do I make one?

Still shoots off projectiles better then north Korea

That looks nothing like a raccoon.

/r/damnthatsinteresting

TIL North Korea has a space program.

Someone call Jamie and Adam

Here's a video of one being made and then launched.

The motion upwards is a combination of thrust from the rocket and angular rotation.. Nice toy but impractical as a design of an actual aircraft i wanna fly in..

Bamboozled

How is it possible that these work better in real life than in Gary's Mod!?

North Korea's new rocket technology.

This is surely at the yearly rocket festival in N.E. Thailand, probably Yasotorn province.

African space program?

NOW THATS COOL!

holy mother of god!

Insert Gurren Lagann Reference

Someone posted this but I'm on a mobile so I've lost the user. Cheers to the explanation found here:

http://en.m.wikipedia.org/wiki/Rocket_Festival

So that's how DNA is made.

Upward, onward.

Does anyone else want to play Garry's Mod now?

Does this remind anyone of their first days in Garry's mod, tinkering with thrusters? Looks like a blast door being launched haha.

That's the chinese space program, huh?

Looks like DNA

LOL eat that NASA.

The North Koreans are getting closer

Slap a gopro on that bitch.

I was expecting the episode of MacGyver where he makes a bamboo rocket.

Shoot for the stars.

this would be great for search and rescue if hikers would carry one of these. seriously if i heard a helicopter and i was legitimately lost i would fire that thing up in an open space.

As a rocketeer myself, i was awestruck at that engineering

you built a rocket out of steam.... awesome!!!!!

Technically, it's called a girandola. You can find some cool pyrotechnic ones @ youtube.com/user/PaOrgRecChaos

Source: I build rockets

This is from a Thai / Lao festival called Bang Fai. There is a great indie flick about it that is available on youtube called The Rocket

What a twist!

North Korea is that you?

UFO's are going "wtf is this shit?"

This is a new one for me and I've shot a lot of shows in the US - thanks for posting this!

Is the bamboo industry a viable industry to invest in?

so that is how spaceX will put humans on mars until 2026

In the pyrotechnics field we call them "Girandola's" often just "dola's". They take hours to build and usually explode into beautiful array of colors when they finish climbing.

ok, KSP, i think the gauntlet has been thrown down.

Does anyone know what type of propellant they are using? cordite-based? Ammonium perchlorate?

Wow the Thai space program is really coming into it's own.

This video just sums up why I love Thailand so much.

that would be some head phuck for the pilots

That guy must've been excited for that launch jumping around like that.

Is this a variation of the hero engine?

Dat username doe

This is super cool and definitely frontpage material IMO.

Powered by Mentos and Soda?

Thats Awesome!

heading over to /r/DYI

Little known fact: bamboo is a grass, it's the fastest growing plant in the world (yes, grass is a plant), and can grow 24 to 36 inches in a matter of a day.

Bamboo is truly amazing versatile stuff.

So that's the explanation for those DNA clouds in Russia.

Seems like North Korea's space program is making progress on their prototypes.

I want one.

Is that how North Korea plans to launch their warheads?

So is china finally trying to go to the moon?

Motherfucking bootleg fireworks.

It looks suspiciously like a flying saucer.

I'm never impressed easily, but that one did for so many reasons.

I'm more surprised that the top comment is not about North Korea and its space program.

DNA Rocket

wait a sec in this case if the circle is spinning faster does the rocket gain more lift?

I was worried this was some strange Asian porn, or sex toy!

DNA smoke.

Good, we will need bamboo on the Moon and Mars if we plan to send Pandas to colonize them!

Wow, that's way more impressive than what I was expecting. I clicked thinking it would be a cylindrical bamboo rocket but nope, we get this awesome cyclone effect rocket.

Well, I guess we now know how Wan-Hu did it.

You know... After two years on reddit, there are days when I forget what's so cool about this website, but then like every day, at some point in the day, I find a link that goes "check out this cool thing from the internet that you would have otherwise never even thought conceivable."

North Korea's space program is coming along.

DNA rocket?

Cause of most UFO sightings.

That may have been the most incredible thing I have ever seen

In this post:

Americans all having their own crack at a China / North Korea space program joke.

Anyone got any more actual information on it?

This makes me tingle in very inappropriate places.

Surely Mr Musk has got a means of using this?

Wow

TIL: Thailand has a space program.

Holy fuck that was beautiful

This is the beginning of learning how to make UFO's!

And here I sit, mouth agape. Not sure why or what just happened, but I liked it.

Zimbabwe's space program is really coming along

Wow, that was pretty darn cool! I didn't think it would get too far off the ground but it achieved great height and looked quite stable.

Anyone else experiment with spinning rockets in Kerbal Space Program? This remind me of that. http://youtu.be/DgPlNj0xCe4

The rocket at 4:20 is the best. "you've created me, now I'll destroy you!"

Edit: Yay cake!

This explains the DNA helix cloud i saw on ifls the other day.

This would be a great nickname for an Asian's penis.

Is this Gmod?

Why yes, yes it is. Now watch as i make flying penis rocket with an explosive barrel as the tip

Wow, that's fascinating.

I think these will be fantastic displays of freedom come the 4th of July. I hope phantom fireworks has a few in stock.

I suddenly want to see this on mythbusters

Am I the only one who thought this looked like a DNA sequence?

That's some crazy zoom!

North korea got an increase in their space program budget?!

damn, i need one of these to carry me from home to campus

Fuck. North Korea finally made it work...

Oh, that's why the pandas aren't having sex. They're nerds.

Look at that double helix.

Not like pandas are endangered or anything

I love the guy in the bottom left jumping up and down and cheering!

Looks like North Korea is testing their rockets again.

I see the Somalian space program is making great progress.

Lord Helix would approve.

Well that's bamboozaling!

woah stop spreading those chemtrails!1!!1

That engine used up a shitload of Mentos and Diet Coke!

I was thinking of this one from Okami

I used to make something very similar, but on a much smaller scale. I used potassium nitrate, sugar and A vodka bottle cap for the casing

This will probably get buried in the comments, but in pyrotechnics, that is known as a tourbillon, and a particularly nice, large example I might add!

Uh oh. Next they will have nukes

Why hasn't someone attached a gopro to one of these things by now?

Yeah, screw gravity!

China, the leaders in wong range rocketry.

Some woahdude material right there

North Korean missile launch

HEAVEN PIERCING GIGA DRILL

This is how China will invade us. All of our advance electronic will not track bamboo.

Call NASA. They need new ways to get people to the ISS now when Russia has become an enemy again.

see how hyped that guy was at the beginning xD

This will get us to Mars

damn chinese can make a weapon out of anything these days.

North Korea still can't get their shit straight.

It looks as though the third world countries have joined the arms race.

Part of me is all like "Go North Korea, Go!" But the other part is all like "Hey, they were gonna eat that bamboo!"

Don't tell North Korea

Well...shit. My stupid Garry's Mod thruster creations weren't all that whacky!

uh, well there went my nasa career, i tought rockets had to be aerodynamic to fly :

This is from LiveLeak, and it's a Thai firework display.

Chinese space program ?

I was in Thailand last year. I was lucky because the annual bamboo rocket festival took place when I was there.

Those things make a lot of noise!

Very cool.

Rocket propulsion in N Korea?

thats actually the best design for a propulsion system. like a spinning top but on steroids!

I made one of those in Kerbal.

pretty gay

(I know the video is Thai) Imagine you're in China, 13th century. You're invading. You have a vast army in front of you and you are confronting the Chinese on the open field. Both armies have assembled into traditional formations, then suddenly the Chinese launch a couple of these over the battlefield, even if they carried no payload and landed no where near you troops, I bet this would cause such panic and disorder amongst the rank and file soldiers that it would ensure defeat.

Meh. Im on mobile so no source or something but wasnt there this story with an army that tried exactly that... Only resulting in free entertainment for the enemies?

yeah, the first time.

Suck it davinche

Wow I would so much suck it

It's good to see the third world countries have got off their ass and started contributing to space exploration.
