Product 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.

Sometimes it is hard to tell the sturdiness of a product when purchasing online. This product is sturdy and well made. It was a gift for my 11 yr old son who agrees that it doesn't look like a toy but has all the fun of one. My son has explored scientific principles with this and I highly recommend it. Delivery service was expedient and well packaged.

I had read some reviews on other versions of this product (from different manufacturers) and became greatly concerned about the quality in terms of strings tangling, poor craftsmanship, plastic instead of metal etc etc... after much scouring and reading of reviews, I finally decided to take a chance on this particular version... the choice was definitely a good one! I found the craftsmanship to be of fine quality, and the balls seemed to line up just fine. My only tiniest of complaints (not even a complain really, but just a minor nitpick) is that I wish the action of the product lasted a little bit longer... but for the price paid, i'd say it did just fine.

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.
