Product Description

NEWTON'S CRADLE Balancing Ball Newton's Cradles are great for home of the office desk! This 6" tall hypnotizing toy will keep you amused for hours. Newton's Cradle of an odd number of identical steel balls each suspended by a bifilar suspension from a sturdy frame. The balls are aligned along a horizontal line, just touching. When the ball on one end is pulled aside and allowed to swing as a pendulum,it hits the next ball. The outcome is fascinating, the one ball on the far end is knocked away from the others with the same speed as the first ball had initially and all of the other balls remain nearly at rest !. If you pull back two balls and let them strike the others,two balls are knocked from the other end, and all the other balls remain nearly at rest. Great for stress relief and makes a wonderful gift! Wood Grain base (5.75"x5") with metal balls.

I got this cradle because I saw that mythbusters episode where they tried to re-create a Newton's cradle with 5 wrecking balls. This cradle looks fairly good aesthetically, but doesn't quite cut it when it comes to performance. When you pull back the metal ball at the end and hits the 2nd ball it starts the transferring of kinectic engery but it starts loosing that energy after each continued reaction untill it conpletely stops. I read one review that said that it because the metal balls aren't exactly the same weight. I weighed them and I got 21.9g=1st 22.0g=2nd 22.1g=3rd 22.1=3rd 22.1g=4th 22.1g=5th
(The metal balls were weighed while still on the strings so I don't know how accurate they are).

The item is very small in size. I purchased it as a gift for my employer's desk, but it was more suited for being a stocking stuffer for a child.

For what it costs this is an incredibly cheap product. It might be suitable as a toy for kids, but if you are looking for something to put on your desk or coffee table this is not it.

The middle wire was broken upon arrival. My grandson was very disappointed. For the price, it was cheaply constructed. Not very good quality.

I've always wanted one of these things. I never knew it was called Newton's Cradle though. I enjoy it. As for Amazon, if they have what I'm looking for, that's where I buy it....Always happy with the price and the quick delivery.

This may not be the best for teaching but it demonstrates the laws used and is fun to play with. The strings seem like they re made of strong fishing line for they havent broke on me

Item delivered on time, as described, great customer service. However, this product is poorly made and I mean poorly. When I took it out of the box and started constructing it tore-up... strings fell apart very cheaply made.
