Classic Desktop Display + Cool Light Show = Fabulous Physics! Here's a new take on a Newton's Cradle with a twist- the spheres all light up and change color! How's it possible? Just push the button and the multi-colored LEDs embedded within the glass spheres are powered through attached pendulum swing lines! Truly fascinating to watch whether illuminated or not! PLUS we've added a mirror to one side, doubling the optical impact! Some assembly required. Measures 7.5 x 7 x 6 . Requires 6 AA batteries (not included). This device demonstrates Newton's conservation of momentum and energy via a series of identically sized swinging spheres. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball outward.
