At first glance, Newton's cradle looks like a complex pendulum, but it is much more: it is a test of two fundamental laws of Physics, the laws of conservation of energy and momentum.
Five chrome spheres each hang from two threads. If you pull the first ball out of balance and release it, then it will stop as soon as it hits the second ball, and the second ball will bounce off with the same momentum as the first ball.
It stands out because:
It is an exquisite decorative toy that fascinates with its simplicity
With chrome plated balls and reticle
Makes an ideal gift for friends and yourself
Demonstrates Newton's third law
