The Newton’s cradle is one of the oldest and 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. This version features an interchangeable single metal frame as opposed to the more common double metal frame cradels. The single metal frame allows for more stability when the balls are in motion.


  • Interchangeable single metal frame
  • Wood pattern base
  • Demonstrates primarily the laws of conservation of energy and momentum
  • Excellent as a desk toy or gift

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.
