Wow I was expecting some cannon with a 3" barrel. :lol:
Nice performance, reminds me of my failed attempt at a mini coaxial.

Heres mine, except it didn't work. :x
It was designed to shoot the ball points out of a pen.

Well it kinda worked, the piston sealed but the pressure pushed the barrel out. Piston was an eraser with 1 layer of duct tape.
Tomorrow if I get bored I'll finish my other cannon, its a .177 cal barrel sealing piston gun in a tee. :D

BTW, how well does that epoxy bond PVC to PVC? Without sanding or roughening up the surface
