When a ball is lifted and released at the end, it will hit the stationary ball and transmit a force through the stationary ball, pushing the last ball upwards. The last ball swings back and hits the almost stationary ball, so the effect repeats in the opposite direction. The device is based on Sir Isaac Newton, a 17th-century British scientist.
