Here is a source for a compressed air "tennis ball" shooter. They also sell a cheaper combustion model but the air model is safer and doesn't produce heat. The local high school bought a "T-shirt sho
ok, FAQs don't say, drawings and pictures don't help... HOW do you get any accuracy out of one of those cannons? do you mount a red dot on it or is it just a matter of trial and error, iow, eventuall

Man, $115, for some PVC pipe, fittings, a pressure gage and valve. However best to pay attention to the pressure limits. My 80 gallon shop compressor runs between 125-130 PSI and 90 on the regulated
My stepson's potato cannon is quite interesting. Has three parallel PVC pipes, two outer ones for holding compressed air, the middle one is the cannon barrel. He loads the air tubes from the air pump
