Newton's Cradle - Demonstrate Newton's Laws with Swinging Balls Physics Science Office Desk Decoration for Over 3 Years Old (Classic)

The product looked and felt a bit cheap compared to other similar ones that I've seen. It was OK and as advertised however, I had a little higher expectations.

Came so tangled I could barely get it apart & in the process of trying 2 of the balls came untied & were impossible to tie back together. Unfortunately the gas it would cost to drive 40 miles to a ups store is more expensive than the item was so in the trash or goes. Very disappointed customer.

I liked this so I bought it as a gift for someone. I liked the design and how easy it was to assemble. Downside is that it got a little shaky as it was swinging and the metal felt a little cheap. 100% worth the price.

My mom mentioned that she had these as a kid but couldn't remember their name. So I surprised her by buying her this Newton's Cradle. She loved it, sent me a video and everything. Easy and cheap win on my end.

This is a perfectly good device as long as no one touches it except a calm and careful adult. My 5th graders broke it in about 2 seconds - they were not supposed to be touching it but...stuff happens. It is attractive, but made from plastic and easily tangled strings. Great prop, but not meant to be messed with.

Tangled quickly, and after two hours of very delicate detangling the strings broke.

Works great!

This is my 2nd one. The first arrived so tangled I returned for a replacement. Took this one to school set it up no problem. But, it's balls stop on their own so it is not a true Newton's cradle.Edit 10.25.And now it has tangled itself all together. Ugh
