Potato Cannon
Yesterday I went over to my friends house. They live in the middle of nowhere, and own a bunch of awesome stuff.
Like a Potato Cannon.
The PC is a piece of PVC pipe, widened at one end. You load it with a rotting potato, or apple, by ramming it down the barrel, using the principal of "Push hard enough and it'll fit". Then you spray hairspray into the widened end, screw the cap on, and spin a very clever flintlock type system that creates a spark inside.
So the hairspray explodes, and sends the projectile really, really far...
Then we started loading it with a rag a a golfball. Then we shot it straight up. We were watching it go up, and then it started drifting, and, well, disappeared.
We haven't seen it come down yet.
