One word of caution: Make sure no by-the-book police find you playing with it, you're not supposed to have them here in NH. I got warned for firing mine down in the sandpits near Concord.

Yeah, it's pretty cool. We're gonna build some more.

You do have to exercise caution with the police around here. I'm surprised that my magnum opus Toy Destruction has managed to stay undetected for as long as it has.

In addition to some combustion ones, Ive gotta jumbo pneumatic cannon. Its tank is a 9 foot length of 4" pvc, with a 1.5" barrel contained inside it. It empties that tank- fast- with a custom made piston diaphram valve. I did a muzzle velocity test with the pendulum method and at 60 psi, it shoots a potato at 450 mph. It can shoot em right through 1.5" plywood or split a 2 by 8.
Its pretty fun...but a certain tree in my yard that is missing alot of bark disagrees
