- This 5.5" desktop display model is a version of Newton’s cradle, a device that demonstrates conservation of momentum and energy via a series of identically sized swinging spheres.
- Classic desktop display piece has become a must have for office decor.
- Swing one steel marble back, let it go, and watch as kinetic energy causes the one on the opposite side to swing the same distance.
- When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball upward.
- Try swinging two or three at once- just don’t pass out from the excitement.
