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

Still works like its ment to but its super small (banana for reference) for the $30 price tag and the bottom is a little light and sometimes it moves. But it works as doesnt come broken in the packaging like other brands

Not what described, it will only move about 4 times then stop, if you’re expecting the Newton’s effect you will be disappointed. Lights are cute but no movement. It was a present and felt really embarrassed to see this worthless things. Boy is obsessed with lights and that is the only reason i won’t return it.

I taught science during VBS. I had several "toys" that kids 5 to 11 enjoyed experimenting with. Several kids and a few parents asked where to get one. I saw a review saying it didn't last long. Well it lasted too long for some waiting there turn! Inexpensive and maybe not high class but kid approved!

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.
