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, as a desk toy/stress reducer, and makes a great gift.
Demonstrates primarily the laws of conservation of energy and momentum

I always wanted one....
Eydie Payne from USA, Scott Depot, WV
Now it is setting on my desk at work. I LOVE IT! When I am having a tense moment, I just listen to the sound of my Newtons Cradle! Recommend it highly!
Ivania Choma from Spiritwood, Saskatchewan, Canada
I wanted a wooden base, because this will be used by a number of children. Very good quality for the price!
Love this desk toy
Teacher Susie from Aliso Viejo, CA
I purchased this for my desk. Every period at least three of my students ask permission to "start the balls"...the middle schoolers love it too! Several students asked me where I got it and several have asked for it as a Christmas present!

My son was so excited when his Newton's cradle showed up in the mail. He showed it to everyone and displays it on his desk. Thanks for having great science products at reasonable prices.
