Potato CannonBuilt: 199X/XX/XX Added to Webpage: 2010/07/19 I made a good potato canon, I think, in the summer between grade 9 and 10 (1998), that used a 1.5' long, 4" diameter combustion chamber, and a 4' long, 2" diameter potato acceleration tube. That potato canon had good kick to it and really sent the potatos flying! It had a slight problem that if something got stuck in it, the threaded back plate would blow off. Unfortunately, it ended up getting confiscated. In grade 10, a couple friends and I built another potato canon, but this time using a 3" diameter combustion chamber and a 1.5" diameter potato acceleration tube. It wasn't quite as impressive or powerful as the first one, but I didn’t have to worry about the back plate blowing off. In the summer of 2006, I was taking a thermodynamics course, which had a project report. A friend and I did the report on the potato canon. It was a very rushed last minute report as we were doing final exams and packing for the Autonomous Underwater Vehical team's trip to the competition site in San Diego the next morning.
