Newtons Cradle Balance Large 7 Balls White Science Psychics Desk Fun Toys

The stainless steel looks very striking on a dark wood end table. It works as described, as an easy-to-understand demonstration of Newton's Laws of Motion. It's a nice conversation piece, but parents take note -- this is NOT a child's toy. It is well-made, but by the necessary nature of its construction, it will break (the strings will break) if handled roughly. Don't let your children tug on the strings. It comes in excellent sturdy packaging requiring no assembly. Just slide each ball carefully out of its styrofoam groove, and the product is ready to display.

I bought this to make up for the fact that my dumb self totally tangled up my nephew’s old Newton’s Cradle while trying to fix it. I wasn’t expecting for my redemption to be broken too. As soon as he opened the box, I was ready to feel better about my dumb self but he pulled out this defective Cradle with an isolated ball. Now I’ll be forever shamed like this lonesome ball.

Save your money or buy something else this is a waste of your dollar

Only get two bounces out of this piece of junk. Returning immediately.

No es algo tan sofisticado como parece ser en las fotos y videos, no tiene la mejor calidad , pero pasa !!

Returning it. The length is too short so there is not enough energy transferred. It works rather sloppily rather than like a precise scientific instrument.

It didn't keep momentum. The plastic that held the balls was thick like fishing line. We returned it..just not impressed

When I opened the product and finished untangling it I noticed that one ball was only connected by one side.
