Newton's Cradle, Large Balance Ball Pendulum, Demonstrate Laws of Motion, Classical Physics Desktop Display, 7.25 Inch Height

My Nephew saw one of there on Youtube and needed one. Looked at a bunch, this seemed like a good price for a larger one. Came quick, no problems and he loves to play with it whenever he comes over.

We have this to our son for his 11th birthday. He loved it and it worked well at first, but after a few days the strings started breaking. Maybe more decorative than useful.

My Grand Theft wanted one because his teacher had one on his desk and he really liked it. The first one I ordered came all things up I had to return it. I bought another one and took a chance. This one was great each ball was individually placed in plastic. It was perfect. The value was good for my grandson

It works like they said it would. Came in the mail very fast and was very well packaged.

Gave as a xmas gift for my adult son, broken in 2 months.

Just the right size fir a deck top conversation starter.

Thank you! I love this thing!

Bought in Oct. but not giving to grandson til Christmas. Hoping it will be ok..corners of box were bent and I haven’t opened it as it is a gift.
