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.
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.
