DIY AirZooka

Using a McDonald’s paper cup, a McFlurry lid, a latex glove (or a balloon), some tape, and scissors, one “MaddHatter” Instructables user shows you how to make a DIY AirZooka paper cup air cannon that blows puffs of air that you can make smoke rings with. If only all science projects were this easy (and this much fun).
