Perpetual motion is the concept of a device capable of moving indefinitely without an external source of power. It's motion is self-propelled and continuous for great lengths of time. Infinite motion is not currently possible because of the laws of thermodynamics, however, you can experience and be amazed at just how long this device will continue to swing after the first drop.
Suitable for ages 8 & up
