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 (or three) on one end, let them go and watch what happens on the other side.
This version features a modern stainless steel base. Great for physics demonstrations, and makes a great desk toy/stress reducer or gift.
Cradle height: 7.5 inches
Ball diameter: 0.75 inches
