It went horribly wrong when a father of young children to light a firecracker in a manhole cover in Xiangtan, China.

:/ unlucky, his arm looks like it got hammered a fair bit

rofl, fucking epic. I've done that a couple of times with the car radiator cap

Alot of ppl claim your fos.

Glad it didn't hit any innocent people walking past.

Some ppl claim the manhole cover on a Nuke Test in the 50's was the first man made object in Space beating Sputnik. (others claim first in space was one of Hitlers V2 rockets in WW2)

What. Also someone needs to dub over the Fus Ro Dah

mad footage. the dude's jacket gets shredded.

I was about to post 'Why does his shirt change colour mid asplosion?'

also, I don't speak Spanish or whatever, did the guy die?

"Stand back kids"...

The plate was never found, but Dr. Brownlee believes that the plate never left the atmosphere (it may even have been vaporized by compression heating of the atmosphere due to its high speed).

What did they use as propellant?

(and was it Methane or natural gas to launch it in OP?)

Also note, dont fuck around in China..there are cameras everywhere!

Re the nuking of the manhole cover:

six times exit velocity.... that's a fair amount of energy to be exerted on a 900Kg steel plate...

Whilst I'm no chemist/physicist, I'm familiar enough with mechanics of how an EFP (Explosive Formed Projectile) works... makes me wonder what the impact of said metal plate would have been had it struck a target.
