VERY simple cannon made form pvc. Its my first gun apart from a simple spud cannon that i got a tutorial for. this one is my own design. Its just a pressure chamber with a ball valve then the barrel. Even though its simple it still shoots great. Watch the vid and tell me what you think.

Good first effort but shame about the ball valve, convert to a modded sprinkler valve and you'll be talking about 4 layers of plywood, not cardboard ;)

Cool but why tap the BV into the cap when you can get proper fittigns and be much more safe? Anyway I like the paint and the gun seems to be effective.
