So, from someone who's never even seen a potato gun, what's the range of those things, fueled by hairspray or compressed air?


Was not my gun, but one of our more creative members put together a length of ABS pipe with a combustion chamber and igniter. Overall length was about 3-4 feet and it was surprisingly accurate after the first ranging shot. Since we were launching from a hill, it seemed to carry 300-400 yards on a good day, using premium hairspray.
