As “mixdenny” says Thai rocket festival.
Happens every year but not always so successful. 
Right on!
Does the rotation of these devices provide any lifting force? - are there any wing elements in there? (I couldn’t really see any), or is it just being lifted by the rockets?
I would say it rises by rocket thrust only. The spinning makes it (more) stable.
I’m glad I’m not the only one who was bothered by that.
It doesn’t do anything!
That’s the beauty of it.
Now that’s the spirit!
Did anyone ever actually find a source for that?
I suspect a uni engineering year or model rocketry club or similar was behind that, the way they were all young men and had team colours and everything, it’s the kind of thing they do.The parachute, especially, indicates that it’s designed for repeatability, whereas most professional fireworks teams seem to go for a spectacular bang and colours over mere height.
Me too. I reported the video actually.
Comments are turned off for the video, which is interesting…
I guess the wheel is about 7 m in diameter, based on the people standing there while lightning it. During the first four turns (about 50") it appears the wheel rises about double the diameter each revolution, say 15 meters. I may have miscounted, but the wheel makes about 60 turns before it burns out. 60 x 15 ≈ 900 meter. give or take 1/3, something between 600 and 1200 meter.
It’s more impressive than Branson’s effort.
It also explains a lot of UFO sightings.
Is it really a racist title if the people posting it are from a third world country?
I’m thinking the parachute is also a bit of *safety feature. The “guidance” of these things is problematic and the impact could be fatal at terminal velocity even for something as flimsy.
*safety - watching on video is a close as I’d want to get to this launch.
Why wouldn’t it be?
And are they?
I’m a little confused. Is it the Ezekiel part or the third world part that is considered racist?
For the same reason it’s not racist for a black person to call another black the N-word.
And yes, the poster speaks Hindi, so I assume he’s from India.
As a person who was born and raised in a third world country, I have no problem describing it as such, nor have I met anyone who did.
Having said that, there are many examples of common terms that eventually come to be considered unacceptable. This may be one of them.
Wikipedia seems to say that the term “third world” is going out of fashion for being too broad a brush and is being replaced by more specific terms that describe more granular stages of economic development.
It doesn’t mention anything about the term being considered offensive (as far as I can tell).
The biggest problem with the title is that is disparaging of a rather impressive accomplishment without even having the redeeming quality of being funny.
The problem isn’t with the term “third world” as such; though I have seen some objections to it, on the grounds that it presumes the primacy of the “first world.”
The problem is with the implication that people in the “third world” are so ignorant that they think this is a space program; or so technologically incompetent that they’d start a space program in this fashion.
