Newton’s cradle or balance balls is one of the oldest, most interesting physics toys that demonstrate the laws of conservation of energy and momentum (and much more). You just raise one or two balls on one end, let them go and watch what happens on the other side. Great for physics demonstrations or as a desk toy/stress reducer, and makes a great gift.

Monica from United States, Plainfield , IL
Beyond pleased with this purchase. Did anton of research before purchasing and I must say this exceeded my expectations. Very sturdy and well made. 12 year old daughter requested for birthday gift. Every morning when she gets out of bed, I hear the click clack of the cradle. Great cost, exceptional product.

Alana from US, Washington
Bought this for my son as a surprise. Did some research into newtons cradles and I am so glad I bought this one. Great quality, which I was worried about.

5 star rating  Really cool gift!
Aly from Washington
Got this for my 19 year old brother who has always wanted one. He loved it so much when he opened it this morning, and it worked really well! My whole family stood around and watched in awe. Great product!

5 star rating  Great Quality!
Lisa from Maryland
After reading many reviews, I decided to order this Newton's Cradle based on all the positive reviews. However, I was still nervous about how the quality would be. Suffice it to say, this one is excellent! The balls are heavy metal and they touch each other (no gaps), and the strings weren't tangled. My son is going to love it for Christmas. (Be careful when removing the styrofoam packaging material to make sure you don't tangle the strings yourself.)

5 star rating  7 inch Newton's Cradle
Monodb from Longmnt, CO USA
Does what I got it for (to give as a present). Displays the results of simultaneously satisfying the Law of Conservation of Energy and That of the Conservation of Momentum.

5 star rating  Elegant toy for the executive nerd
Walter LeCroy from US, NC, Hendersonville
Clean, well-functioning implementation of the classic conservation of momentum demonstrator. Very nicely done - an elegant toy for the executive nerd.

5 star rating  Excellent Product
Luanne from Hoffman Estates, Illinois
I am perfectly satisfied with this product. I am glad that I had read a warning online about unpacking it carefully. Filaments may get caught on some styrofoam packing material. Be careful and you will have lots of enjoyment from this well-made product

5 star rating  Really fun!
BigBlueToe from Central Coast, CA
I teach 4th grade. I bought this to put on my desk because I thought my kids would love playing with it. They do! It's just what I wanted.

MCT from Virginia
Great quality - wonderful gift for Granddaughter - illustrating principle of physics and fun too!!!

5 star rating  awesome

way better than those terrible ones on amazon that cost just as much as this one

4 star rating  works well
Bookseller Guy from St. Paul, MN
Looks good on my desk. Balls are level and it works. It's not super solid so the balls lose their momentum relatively soon. Overall for the price it's really good. Kids love it too.

5 star rating  Desk top gift
Michael W. Beattie from USA Milwaukee, Wisconsin
I have always thought that this was a great desk top item.

5 star rating  Excellent Product
Ken R from Des Moines, IA
Found this after a long internet search of smaller, cheaply made products. The weight of the balls is what's needed for this to work correctly. My 9 year old granddaughter loved it!

The Newtons Cradle arrived quickly and in perfect condition. It was a real hit with my grand-nephew who is 10 and in 4th grade.

5 star rating  Ever a delight!
Beverley Sutton from Tucson
Used in a science class to demonstrate Newton's Laws of Motion and the Conservation of Momentum. The students were endlessly fascinated by it and came up with some creative combinations. Product is delicate though, watch youngsters carefully.
