Re: Potato Guns/ Air Cannon's

The best one me and my friend made was out of PVC pipe. It fit tubes of caulking PERFECTLY. The BEST combo we ever found was using a grill ignitor, white lithium chain lube for fuel, and we put a valve core in the side of the chamber to pump a little air in to mix everything up and burn hotter and faster. We found one of the tubes ONCE, it was at least 300 yards away
