Mini Newton's Cradle table toy

Add some physics to your desk or table! Newton's Cradle demonstrates the law of conservation of momentum and energy through a series of swinging balls. You can witness the amazing laws of physics wherever you place this device by picking up one of the end balls and releasing it, and watch the magic happen! Promotes relaxation, relieves stress and increases inner peace, great for conference rooms, lobbies and offices!

Since the beginning of Newtonian physics, science has shown us time and time again that we can build incredible demonstrations that interpret observations mathematically. This Newton's Cradle does just that with its identical pendulums in a series that illustrate Newton's laws of conservation of momentum and conservation of energy. The toy was originally created to entertain people and was invented in 1967 by English actor Simon Prebble, but was named in honor of scientist and mathematician Sir Isaac Newton.

The premise of the toy is to take one of the steel balls at the end of the toy, rotate the pendulum 60 degrees from the vertical axis, release it, and watch as the falling ball transfers energy to not one, not two, not three, but four other steel balls. This in turn sends the adjacent steel ball up to almost exactly the same height as the original ball was lifted. When the second end ball begins to fall from its maximum height, it will convert its potential energy back into kinetic energy, which will again move through the system, and the system does this indefinitely. Now, due to friction against the air and heat loss due to the elasticity of the material, the spheres will eventually lose their repetition, but you can still see that only a small amount of potential energy added to the system can live inside the system for a large amount of time!
