Newton's Cradle Amazing Balance Balls Pendulum Law of Physics Science Office Decor Smart Toy, NEW!

A Brand New Item in the Original Box!

The Perfect gift for Anyone ~ Not just for Geniuses or Geeks, lol!

This fascinating pendulum phenomenon demonstrates the Laws of Physics and shows Conservation of Momentum & Energy.

Size: Length 9cm long x 7cm wide x 9cm high
Includes entire display: 5 steel balls, sturdy plastic frame & base

This classic piece has become a must-have for home and office decor. Pull one or two steel balls back, let go.. and watch- kinetic energy causes the ones on the opposite side to swing out the same distance! This 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. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball upward. Because it uses Newton's Laws, it was named after Sir Isaac Newton, English physicist, mathematician and astronomer, but was actually invented in 1967 by an English actor.
