Working principle

The jumping disc is made from a special piece of metal, called bi-metal that moves when heated with your thumb. When it is warmed to about body temperature, you can “click it” into its loaded position and then carefully place it on a hard surface. When it cools down to room temperature, it suddenly snaps back into the old position, and simultaneously jumps high up in the air. It jumps several hundred times its own height.                                              

The jumping disc works on the same principle as a thermostat or a shunt-valve in your car. With such a thermostat or automatic valve, a special piece of metal, called bi-metal, moves when heat is applied or removed. Bi-metal is actually two pieces of thin metal fused together in the middle. When the temperature changes, the metals expand differently and bend into a curve in either direction.
