Westminister Inc. – Newton’s Cradle Balancing Balls Science in Motion Wood Grain

Bought a different one originally but it arrived damaged. I read so many bad reviews about pretty much ALL of these, but this was what my 6 year old wanted more than anything for her birthday. I tried this brand after the first didn't work out and it has held up well. Works as expected. The kids often get it tangled since they are really too young for it (I also have a 4 year old) and it is easy to untangle and hasn't broken yet to my surprise!

I purchased this for my grandson who really enjoys it. The whole family enjoyed playing with it, too. There was only one problem which was not the fault of the toy. It was the fault of my granddaughter who played too hard with it and caused it to get tangled. Then I had the job of getting it untangled. So much "fun"! My suggestion is not to let children under the age of 10 play with it unless they understand how to properly use it.

I bought this to be used for a grade school physics class I teach. It worked perfectly. The students couldn't stop playing with it. They were fascinated by the principles being displayed. That fostered a half hour of lively discussion that really imprinted some of Newton's laws on their minds. It has adequate construction quality to be used for demonstrations, but probably wouldn't hold up if used a lot or abused by children who can't seem to keep from trying the limits of such a tool.

First of all, I don't see a Newton's cradle as a toy. Newton created it to display certain laws of physicsSecond; I'm not happy with this product. The center ball is supposed to stay stationary and the outer balls are suppused to continue rocking back and forth in perpetual motion for at least a long period of time. The one I recieved wouldn't maintain the intended action for even a minute.A Newton's cradle was always a thing of beauty to me. I finally bought one for the first time. This one. And upsettingly it didn't perform or bring the calming sensation I always felt when I've been around a fully functioning one.But at least I have one now to look at. It's a good decerative peace. So it's not all bad.

I bought this as a desktop toy, I expected balls to be colliding for at least 2 minutes but that didn't happen. Metal balls are balanced with strings but the space between every string isn't the same so that cause the balls to stop. I don't recommend buying it!

great low price, product exactly as shown, and is completely fine. Other reviews may say cheaply made, but I disagree. It is made well, I bought two of these (identical, same company) for me to use in the classroom as an illustration of kinetic energy. My students are PRESCHOOLERS and it serves it's purpose just fine. Thank you for a great, affordable product!!! I will buy more as my program expands.

This is a nice classic item, well made, without any cheap appearing components. My son has his on a table in his room, and will just sit there and watch physics in action without realizing it (for every action, there is an equal and opposite reaction).

My wife was dubious but since I am a former physics teacher how could i not give it to my 6 year old grandchild. He loved it, playing with it for five minutes two or three times Christmas day. Not bad for a little toy. More importantly, he knew what would happen after a few tries and in a few years may get some real understanding because of it.Note, it is small and toy-like, if you expect the steel balls to bounce for minutes you are out of luck--five repetitions is about all it can do, sometimes. For quality, fanatics and/or teachers can spend a few hundred dollars or use the internet to learn how best to make one with old bowling balls.
