Calcium carbide is an electric arc furnace from a mix of coke and lime at 3600°F. But you're not here for that right? You want to see explosions and rockets, that's why Crazy Russian Hacker made this video!
A cup over a bottle containing the chemical solution, a bit of heating with a lighter and boooom, the cup hits the ceiling. Science.
And has the crazy Russian hacker would say, safety is the number one priority so don't do this at home.
