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 use this in my high school science class to demonstrate Newton's principle of force and reaction. The students were completely intrigued with the cradle. It was much more fun to use this as an object lesson than to just try to explain the principle verbally in class.

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.

Flimsy fun. Have to treat this thing to a cushy life or these strings get so tangled you'll need a miracle to untangle it. My 10 year old son wanted it so bad... I got it for him and he has enjoyed it the first week. New it sets on his dresser collecting dust. I untangled this blessed thing so many times during the week I was about to pull my hair out. So, its fun.. its flimsy. End of story.

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.

Whole item made of plastic, when you swing the metal ball the whole structure wobbles

Everything was great. Speedy delivery.
