10 Jumbo Popping Hoppers - Colors Vary
Flip these flexible Hoppers inside-out and place them on a hard surface. Stand back and watch them POP into the air. These Jumbo Hoppers measure 2 inches in diameter. If you invert them and drop them on a hard surface they bounce to a higher level than it is dropped from, seeming to defy conservation of energy. It shows that energy can be stored in many ways besides potential and kinetic energy. They are made from a rubberized material that allows them to release the power of natural tension after they are turned inside out. This natural tension is the energy that makes them soar, dropping it is the "activation" energy. This is a fun activity for any Physics or Chemistry Classas well as an exciting Party or Group Activity.
