Do you like animation? How about potatoes? How about guns?
Watch this animated video tutorial to see how to build a potato cannon (or spud gun). You're going to need some supplies, like some hairspray, a lighter, some PVC, and perhaps some potatoes. Just put them all together and you have one powerful spud cannon. Just be careful not to attack any farmers, they might not appreciate it. So, instead of eating mashed potatoes, mash them on the ground after they've flown through the air from you very own spud gun.
