Balancing Ball Newton's Cradles are great for home and office desk! Great for stress relief and makes a wonderful gift.

 Newton's Cradle is a device that demonstrates the conservation of momentum and energy. It is also known as an executive ball clicker.

If you pull back two balls and let them strike the others, two balls are knocked from the other end and all the other balls remain nearly at rest.

Great for stress relief and make a wonderful gift.
