Video: How to launch 55-gallon barrels into the air effortlessly

Need a reason to not fall asleep in chemistry class? How about learning how to shoot barrel drums into the air just by touching them with fire? If only chemistry class was this much fun, we'd have paid more attention.

To get the barrels to fly into the air requires a little bit of know-how. According to Kottke:

If you mix calcium carbide and water, it produces acetylene. Acetylene is extremely flammable and can launch 55-gallon drums into the air when ignited.

That sounds easy enough. But wait, don't attempt to do this without supervision and a really large open space because those barrels will come back down. And if you're not careful, they could hit you.

Happy barrel blasting!
