### ⭐⭐⭐⭐⭐ SPECTACULAR SCIENCE TOY!
*by E***. on December 15, 2025*

A perfect toy that demonstrates inertia, the law of conservation of energy, elastic collisions, and related topics. It arrived in a well-preserved, properly packaged box and the device works like a charm!

My sons were surprised. They liked their gift, as it goes way back in years.

### ⭐⭐⭐⭐ Newton's Cradle
*by M***A on January 25, 2024*

This is the second one I purchased as I'm looking for one that has sustained movement and works synchronously. This one is better than my first and the individual balls have moderate weight so it has sustained movement for less than a minute. It works n stand is sufficient for purpose of demonstration. If looking for a more precise n sustained movement, I'd suggest one with much heavier balls but you'll probably have to pay lots more. This one is good for the purchase price.
