Just was thinking, would the ATF consder potato cannons AOWs or destructive devices? I kind dought they do though, never head of anybody geting in trouble by the law with them. Was cleaning shop yesterday and found my old one I made when I was a kid.... anybody think I could sell it here? I wouldn't know anyone who would want it and its just takeing up space and colecting dust.
josh-

No you can make and still enjoy them.

Thumper X-1
120 yards w/ 8 ounce paint balloon is my best to date.

Got a pic? Share with the class?

I wish I had a camera, Mines a air one too, the farthest I've ever shot it was about 200 yards at a silo with 200psi I belive, and a very tight spud. That was a pretty big arch though. You ever shot stones or water out of yours? Back when I was like 16 I riged a bunch of spears with spacers so they would always go straight. I also made a wooden bullet one time and made little rifleing fins on it too, really cool to shoot but I lost it after a few shots lol.
