In this video I'm bringing together a bunch of different spud guns that I've built, to see which design performs the best! We measure a number of factors including muzzle velocity, accuracy, reloading time, and more!

The video also features a couple special guest cannons of different designs. As far as I can tell, this might be one of the first "scientific" potato cannon comparisons!

The first half of the video is test shots and measurements, and the second half are mostly graphs and slide-shows (I'm sure to win the middle school science fair now!). Skip to about 12:54 for final conclusions on what's the best!
