Suck my flaming rocket balls!

I don’t get the copper pipe part. Please describe fully.

I promise not to do this in the house :slight_smile:

Hehehe. We did this but instead of a copper pipe we built launchers out of empty soup cans.

So it’s more of a potato cannon then a tennis ball glued to a bit of copper?

Kind of, but we launched tennis balls with it and when we put the alcohol in it to launch it the ball caught on fire before bouncing around the science classroom. We caught a bunch of paper decorations on fire too…it was awesome!
