LED Newtons Cradle

Batteries:4 x AA batteries(Not Included)
Your preschooler will love this glowing Newton's Cradle. And its more dazzling at night, thanks to the base which has a luminous plate, projected onto the glass beads.
The Newton's cradle is a device that demonstrates the conservation of momentum and the conservation of energy with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.
