Product Description

Product Description

Newton's Cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy. It is also known as an 'executive ball clicker'. Newton's Cradle is one of the classics from the 80s that is making a comeback as a retro desktop stress reliever. A classic executive toy and makes an ideal desktop gadget!

Product Description

Who would not know the famous Newton-Pendulum; it demonstrates the laws of momentum- and energy conservation in a very descriptive way.
Iy you let one of the 5 balls swing against the others, the energy is only transferred to the one on the other side of the row.

Dimensions: Frame: 13,5 x 11 x 10,5cm
Balls: each 1,5cm in Diameter

3.0 out of 5 stars Best of a below average selection 11 Mar 2012
By Clavain
Durability: 3.0 out of 5 stars    Educational: 3.0 out of 5 stars    Fun: 3.0 out of 5 stars   
I like Newton's cradles. I like the opportunity they present to discuss conservation of energy. I also like the sheer mesmerizing effect of the balls clicking back and forth, and the different patterns you can make.

There is a tendency with these toys to be made very cheap and lightweight. Unfortunately this leads to more of the energy being transfered in ways that aren't so pleasing on the eye. In this case after 20-30 seconds the clicking stops and all the balls just swinging slightly. I've seen others that are worse, where the show last less time.

I wouldn't say this is a bad toy, and indeed out of the ones available at the time of purchase, it was probably the best I could find. It was pretty cheap, and therefore satisfactory. However if you're after a long-lasting effect, you're going to need to pay a lot more.

Product was good quality and packaged well. I thought it may have been a little larger - it would have helped if the size were stated in the product description.

2.0 out of 5 stars Arrived Broken 28 April 2012

Durability: 1.0 out of 5 stars    Educational: 3.0 out of 5 stars    Fun: 4.0 out of 5 stars   
I read the reviews prior to purchase, so I suppose I had been warned! Other people had had similar experiences.
This smaller model is very flimsy and one of the nylon barbs attached to the balls was broken and there was no way you could fix it.
I returned the item and got a refund quickly so no moans there.
Still really good educational gadget. Just get the slightly larger and I presume sturdier model.

I bought this for my nephew and I was not impressed. It doesnt keep its momemtum at all not to mention how flimsy it was. I don't care how much you pay for something. Its still hard earned money and you spend. No not worth it.
