Potato guns

My Scout troop has 3, all about 5-foot long PVC. Fuel: hairspray.

Our Mechanical Captain actually made one during the build season. It was really powerful though; almost crossed a football field and even more.

I'm gonna be building one once school gets out (last class is Friday morning). I want something to mess around with when I get bored and to play with when I have my bonfire this summer.

God i feel like a retard, how do I put pictures in?

That picture of someone holding a potato cannon on their shoulder should be on the Darwin Awards website. PLEASE do not hold a potato cannon next to your head when you fire it. About 10 feet away with an electrical switch is about minimum. Behind a row of sandbags would be better.

I especially disapprove of holding the combustion chamber next to the head. Really, really dumb. Really.

Disclaimer: my son and I own and operate a small cannon. I've never held it next to my head. I have talked to owners of exploded cannons.
