Electrothermal Fragmentation Cannon of Doom

video Electrothermal Fragmentation Cannon of Doom

This was something I made when I was bored. It's basically a barrel made of K'nex, with a small capacitor stored in the barrel. When current is added backwards to the capacitor, it explodes, ejecting shrapnel out of the end of the barrel and at the target.
Also, the smoke smells strangely of popcorn. Inhaling it gave me a headache. Do not attempt.

I might as well use a cheap little LED and add high voltage and BOOM! I didn't see the silicon chip in there so I assumed it either turned into little pieces or vaporized.
