Commonly known as an “Executive Toy”, Newton’s Cradle has long been a fascinating gizmo for many people. I always had one on my desk. It has also been used as a classroom model for demonstration of Conservation of Momentum. Now a futuristic dimension has been added to it where the metal spheres have been replaced by glass spheres that each sport bright, multicolor LEDs, hence the name – the Kinetic Light Newton’s Cradle.
Designed and manufactured exclusively by ThinkGeek, this wonder toy will relieve all your stress when you are in the middle of stressful task. Just dim your lights and let this gizmo do its work. The lights on this advanced Kinetic Newton’s Cradle will react based on their position, where starting a kinetic chain reaction with one ball will let you observe how the others change color in response to impact every time.
Takes 6 AA batteries that will power it for 13 hours of uninterrupted action. The Cradle weighs about a pound without batteries. It will cost you $49.99. Batteries not included.
An added value would be if the gadget could also be powered from the main supply. Buy It: $49.99
