Did this video help you?

Sam Ryan: So does anyone have a rough estimate on power for this thing? It looks like it works really well, and even seems more reliable than a combustion potato cannon(no cool flames unfortunately). But my big question is, if you made the valve in the back larger would that give you more speed with more space for air flow? Also could you instead of making the valve on the back, run a tube from there to the front so you could hold it like a bazooka?

sonic boom: I shame myself being an engineer, still hoping to get the mechanism

Robert Nash: how does having a ball valve on the rear make it fire in the other direction?

LOUIEVIL 7.62: I am trying to build a bait caster but the ones on the videos require stands and feet and legs in two different chambers and all kinds of crazy stuff this is two Chambers one inside the other and I could carry in my hand do you think it would be a good baitcaster I will be happy with reaching 200 yards or so the ones everyone is making its usually 300 to 350 yards on 90 or 110 PSI please comment back

Ace Rimmer: I want this in a Giant Revolver.
Busta'Rhymes style !!

ThePyroDUCK: Man what can i use instead of the tee caps? Like how do i make a different piston and from what??

WreklessGamer: Night hawk is there a way I can contact you that isint on YouTube?

Amador Contreras: I also have a small leak coming out of the barrel can you help me please? I used 320 x fine sand paper is that good enough? I got my tee caps on eBay but still a small leak

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???

lander holsinger: Could I shoot water balloons out of this with a wadding of some sort

Jeremy Conrad: can i use this to launch confetti?
