BesnanLy Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of 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.

The last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction.

The beautiful colors and the fact that the balls move smoothly for an average time of 20 seconds make science more fun
