A typical Newton's Cradle toy on a desk at the office not only alleviates boredom through hypnotic swinging balls, it also demonstrates Sir Issac Newton's law of conservation of momentum. The cool new Kinetic Light Newton's Cradle does all these things, but adds fun illumination as well. This fun executive ball clicker replaces the standard steel spheres with frosted glass embedded with multi-color LEDs. Simply lift one, two, or three spheres, drop, and watch in amazement as they perfectly transfer their energy through the rest of the spheres and fling up the same number on the opposite side. In addition to the satisfying click-clack sound as the balls swing back and forth, they also change color as well. When they finally come to a rest, simply repeat the process until it's time to head home.
