Witness the amazing laws of physics! Named for Sir Isaac Newton, Newton's Cradle demonstrates the law of conservation of momentum and energy via a series of swinging spheres.
When one of the end spheres is lifted and released, the resulting force travels through the line and pushes the last sphere upward. This chain reaction of swinging and clicking balls is quite entertaining and mesmerizing to watch. A creative, high-quality gift you'll be proud to give to someone special, and this Newton's Cradle can be a great teaching tool. Great for conference rooms, lobbies,offices or even in a kids room. It is just plain fun!
