Newton’s cradle or balance balls is one of the oldest, most interesting physics toys that demonstrate the laws of conservation of energy and momentum (and much more). You just raise one or two balls on one end, let them go and watch what happens on the other side. Great for physics demonstrations, as a desk toy/stress reducer, and makes a great gift.


  • Demonstrates primarily the laws of conservation of energy and momentum
  • Excellent desk toy
  • Perfect for physics demonstrations
  • Cradle size: 5.50in x 5.50in x 5.75in
  • Black wood base
  • Chrome metal balls

Note: This product is not meant for young children. It is a delicate object, meant for use as a desk toy or fun stress reducer. Balls on cradle can get entangled or snap off if not used properly.

I wanted a wooden base, because this will be used by a number of children. Very good quality for the price!

Teacher Susie from Aliso Viejo, CA
I purchased this for my desk. Every period at least three of my students ask permission to "start the balls"...the middle schoolers love it too! Several students asked me where I got it and several have asked for it as a Christmas present!
