I remember the first time we fired one of these. It was dusk and my brothers and I had rigged a remote igniter, and I was elected to hold the cannon itself. We loaded it up, sprayed hairspray in and my brother pushed the igniter.
None of us had any idea of how powerful one of these was! The flame that came out the front was over a foot long. We thought maybe the potato would reach the back fence of our yard, but it was launched into oblivion. Luckily our house backed up onto a nature preserve, so at least no-one had a surprise potato land on them.
We had much fun that summer iterating on designs and trying every type of various projectile we could find.
- lagniappe 2y agoYou probably started a small field of potatoes if it stayed mostly intact!
- mavamaarten 2y agoI remember shooting a potato into a wall, hoping to laugh at the potato becoming mush. There was no mush. Only potato dust.
- rolph 2y agoyou have to freeze the potato for more "lolz"
- RicoElectrico 2y agoIf you freeze it, it won't cut to the diameter of the barrel.
- rolph 2y agoyou make a number of spud pellets, you freeze them after
- BizarroLand 2y agoI like how when someone offered an idea that turns a mildly dangerous toy into a decidedly lethal weapon, rather than dissuade others of the terrible notion we went into problem solving mode to increase reliability, quality, and to minimize the potential hassles inherent with the lethal solution.

- ahartmetz 2y agoSame with an apple, only a wet patch on that steel door. Bouncing potatoes off the surface of a lake was fun, too.
- sandworm101 2y agoYou get better range if you swap out the hairspray for black power, and the barrel for a metal pipe.
