Review: Cats loved it. - This product was 'needed' for a lesson in physics in my homeschool. The kids enjoyed it, it demonstrated what it needed to demonstrate. On morning two, however, it was ridiculously tangled and I got annoyed with my kids (ages 14-9) because I had explained carefully to be easy with it. Untangled (which isnt great, but is doable). The next morning, however, my husband was the only one up, getting ready for work and heard this item clicking. The cat had discovered it, lounged out on the table beside it and figured out how to pull back the end ball and then proceeded to spend the next several minutes watching it swing until it needed to be reset. So, overall, this item pleased every member of our household, including the cat. The cat, however, did not take any responsibility for untangling the mess he made out of it.
Review: Highly recommend!!! - Great price for this. Gave this as a graduation present. Material and size are perfect.

### ⭐⭐⭐⭐⭐ Newton’s Cradle and young children
*by C***N on July 6, 2026*

I have discovered that children cannot resist tangling the balls up. I have learned this the hard way by spending several long sessions with a good light and a magnifying glass to untangle. Now I keep mine in a less accessible location.
