I'm asking because I want to make a marshmallow shooter for large marshmallows
The-T-in-buffet: For a physics project I have to launch a potato 75m, is the barrel long enough? Would the bike pump pressure be enough to launch it that far without exploding?
James Miller: If you can find a way to open the valve faster like using a spring or something, the cannon would be a lot more powerful
Taran Ahluwalia: Does anybody know if a hockey puck actually works in replacement of the galvanized steel gas vent tea caps?
man4thwalt: I built this cannon, but it's not working. After airing it up to 40psi, when I open the valve all the air escapes out the rear of the valve. Do you think that I need to back out the barrel a little???

Rivera John: hey @NightHawkInLight i need help
Rivera John: ive built one but w a lil variation. i posted pics in my paintball chat group on facebook. i would like to tag you and give credit...
Rivera John: hey I got a question. instead of reducing it down to half inch with a ball valve have you tried using a 1-inch sprinkler valve? I used it on my air cannon and it works great. I know I have an air nozzle screwed into the side of it to dump the air but I guess you can keep the solenoid on it and install a battery box and Trigger towards the front of the launcher so you can fire it shoulder-mounted and w a pistol grip instead of turning the valve at the very end. that's what I plan on doing with this design that you have shown us. also have you found an alternate solution for the valve instead of having to fabricate one w those caps?
Kpomal productions: The cannon can also be converted to a potatoe gun
