InGenious Newton's Cradle Five Pendulum Classic Physics Swinging Executive Desk Toy | Physical Pendulum, Balance and Relaxation, Executive Gadget Scientific Educational Decoration for Adults and Children

Solid base, well made frame - works well. Do unpack it very, very carefully though!

God value Newtons cradle , performs well for the price compared to some very expensive alternatives.

Its quite fun, but it doesnt go for long so could be better but its alright for the price paid. Fairly sturdy.

Quality purchase and good price.

Decent size for value and a really good gift

Bought for a friend, he's very happy with it.

Got this for my Grandson for his room and he absolutely loved this he was showing to all his friends after Christmas. Unfortunately one of his friends played with it and it got all tangled and none of us could get it untangled which is such a shame as he’s really upset. But we hopeful of getting it fixed. We have asked all family members now we are asking friends. Fingers crossed.

I was very pleased when I opened this, since it looks really nice. I was disappointed when I actually tried it out. It is larger than I had realised (considerably larger than some more expensive ones) and looks well made. As a physics teacher I play around with this type of thing occasionally but I bought this one as a toy rather than for teaching. It seems the challenge of manufacture is to make the balls impact and leave cleanly (elastic collisions, where one ball exits while the others stay still). I thought this version might be better than the small ones. I was wrong. The balls do not show the pleasing behaviour expected of Newton's cradle very well. They ricochet off each other and within very few swings they are all moving together. I'm guessing I need to pay a lot to get one which works well, or maybe small balls actually function better than large ones?

Well packaged so the balls and strings were secured. It works really well. I immediately tried it, lifting first one ball then two then three. All options worked as expected. There is a very satisfying click when the balls hit. I was surprised at how long the balls kept swinging. The base is stable. There is no wobble at all. And it looks really good. The balls and supports are chrome so they are nice and shiny. The strings are almost invisible. I definitely recommend this and I would buy it again.

* Good quality metal used * Sturdy as it's little heavy

FUnciona como debe y no se cae ni se desmonta

Mouais… Qualité médiocre, on ne va pas se mentir. De plus, cela dure une minute et 15 secondes à peine, j’ai vu mieux, bien mieux! Je trouve ce produit plutôt chère du coup (24€)

Pendolo classico e resistente, le corde non si intrecciano ed è molto educativo.
