Newtons Cradle Balance Balls TWO DAYS FAST AND FREE SHIPPING SATURDAY DELIVERY SERVICE Store Payments Shipping Returns Terms Newtons Cradle Balance Balls 7 1/4 inch Description: Newton's Cradle is a timeless, classic desktop science "toy" that is the perfect blend of science and art. Lift one steel ball and allow to fall back at one end, the ball at the opposite end will swing out the same distance. Stylish chrome and black color scheme. Fascinating to watch. Also known as "Balance Balls", "Newton's Pendulum" and "Newton's Balls", this executive office toy demonstrates the law of conservation of momentum. Using Newton's third law has never been this much fun! What happens when you swing two? Or three? Newton's Cradle was invented in 1967 by English actor Simon Prebble and named in honor of scientist and mathematician Isaac Newton because it employs Newton's Laws. Newton's Cradle makes a great desktop gift. These swinging balls will keep you occupied for hours at work. Newton's Cradle is a clever device that not only demonstrates a pendulum, but also shows the Laws of Conservation of Momentum and Energy. Product Dimensions: 5 x 7.2 x 7.5 inches ; 1.9 pounds Video: Customer Reviews: I purchased this item for my 11 year old grandson. It arrived very quickly and his parents said he was thrilled when he received it. He called me to thank me and I "listened" to it operate over the phone. He has had it a few days now and is still enjoying it. I am a bit surprised. I thought it would be something he would get bored with quickly, but apparently that is not the case. He did tell me if you hold the balls too high, the strings will get tangled, however, they are not hard to untangle. So, this item is a hit with my grandson.
