Rain down cotton balls on family and friends with the Cotton Ball Launcher! The Cotton Ball Launcher is a simple STEM craft that makes use of simple household items as materials. The Cotton Ball Launcher uses basic principles of energy and momentum to launch a cotton ball projectile. By loading the launcher with a cotton ball and stretching the rubber band hammer backwards, elastic potential energy is stored- the energy gathered when something is twisted, compressed or stretched. When you release the pencil, this elastic potential energy is converted into kinetic energy as the rubber band hammer surges forward, colliding into the cotton ball to launch it out.
