Which is why I was asking.

hmm i dunno then, it won't really work with aerosol unless the ball is suspended half way up the barrel to give a chamber.

maybe you could liquefy propane :D

I suggest you have your parents or a responsible adult buy off and support what you're doing with your cannons....believe me it's better that way. Yes, it may take some lobbying effort...

I just used mine today for the first time. I wasn't impressed. Is there a cb ratio that I missed somewhere? I used lighter fluid. I did get a pop but not what I expected. I used the one here as a template

I guess I'll try 2 more cans...Later

You'll need to sabot the tennis ball with something....a small rag or something... as standard cans are a little larger than the steel Pepsi cans were back in the day. Also, drill as large hole as possible in the center of the "spoked wheel".

It will work, trust me...although nothing as impressively as today's cannons. You've just got a little too much blow-by with the tennis ball and today's cans. Also, be sure to keep the lighter fluid squirt small.

Expect the cannon to get much hotter than pvc cannons you are used to.
