Colored Glowing Newton's Cradle — LED Desk Physics Toy

Newton's Third Law, conservation of momentum, and conservation of energy — all at once, glowing from your desk. The Colored Glowing Newton's Cradle demonstrates these principles with each satisfying collision, with the added effect of LED lighting that makes the physics hypnotically beautiful in low light. Pull back one ball, release: exactly one glows and swings out the other side. Pull two: exactly two.

The mathematics of elastic collisions made visible and luminous. The glow effect makes this a standout desk toy that's also genuinely educational — the physics is the same as a standard cradle, just more dramatic.
