Building a mini-potato gun
To clarify, this doesn’t involve mini-potatoes. It uses a potato “slug” the diameter of a pen. And the fuel is hairspray, so you’ll need to carry some into battle with you. You’ll also ruin a perfectly good butane lighter. But if you’re really bored and not worried about losing your eyebrows in a freak accident, this might be the project for you. View the video here.
