Cotton ball launcher is an easy science experiment that explains the physics concepts kinetic energy & potential energy.This launcher explains about the elastic potential energy. This working model can be used in the school science fair project. A fun science experiment to understand about elastic potential energy & also conversion of elastic potential energy in to kinetic energy. You can launch cotton ball , pom pom etc using this launcher. Making this launcher is a fun stem activity. In this video we make 2 different type of launcher, Cotton ball launcher & cotton swab launcher. More fun can be added to this easy science experiment by painting & decorating the launchers.
You can make the cotton ball launcher more interesting by experimenting with different length pencil , paper roll etc.
