CERROPI Newtons Cradle Pendulum with 7 Balls, Classic Swing Newton Balance Ball, 30+ Sec Swingtime, Science Physics Gadget, Desk Toys & Office Gadgets for Desk Decorations

This was a birthday gift for my 12 year old grandson! He loves mechanical things and this one was a big surprise to him!

Kids loved it - packaged nicely- good quality

This is the second one I purchased as I'm looking for one that has sustained movement and works synchronously. This one is better than my first and the individual balls have moderate weight so it has sustained movement for less than a minute. It works n stand is sufficient for purpose of demonstration. If looking for a more precise n sustained movement, I'd suggest one with much heavier balls but you'll probably have to pay lots more. This one is good for the purchase price.

This was perfect and fun until the cat found it

Nice pendulum. It comes really well packed. It was a gift for my sister and she loved it. Good size to put on her desk.

just okay quality, not like the ones I remember as a kid.

It is really nice for what it is. A cheap “Newton’s pendulum” Good Clean construction. Very well made for the price. Has a silicone sticker to act as rubber feet. So it won’t mark furniture and will not slide. My Son (9 old) LOVES it. He is so Happy to have it on his gaming desk. This is not gonna last five minutes for its size. It went for about 46 seconds instructions said 45-55 seconds. So it does what they claim it will do. And if my son ever gets tired of it. It’s going on my office desk 😉

This item says a direction booklet comes with it to fix it if it’s broken. It also comes with and extra ball just in case. Well I didn’t receive any directions but did receive the ball. Of course it broke right away and I have no way to fix it. Tried contacting the seller but got nothing back.

Just what the kiddo asked for at Christmas. Full size as expected.

子どものおもちゃや飾りと考えたら楽しく 思える品物です。 ブレもあり 精巧性などを追求しなければ良いです。

Good Quality

Bought the CERROPI Newton’s Cradle Pendulum as a gift for my teen son, and I’m happy to report it has survived teenage handling (which is saying something). It now lives on his desk and is used equally for “studying,” stress relief, and dramatic staring while procrastinating. The clicking sound is oddly satisfying, the motion is mesmerizing, and it makes him feel both scientific and deep—like he’s contemplating physics… or what to eat next. It’s sturdy, well made, and somehow calming, even when homework is not. Great little gift for teens, science lovers, or anyone who needs an excuse to stop working and stare at swinging balls for a minute. Would absolutely buy again.

This toy is simple but very relaxing to watch. The Newtons cradle with 7 balls swings smoothly and creates a nice rhythm that is calming after a long day. The build quality is decent and it looks good on a desk or shelf. It is also a fun way to show basic physics in action, especially for kids. I like using it when I need a short mental break. Just watching it swing back and forth is surprisingly satisfying. Overall, this is a nice and relaxing toy that is both decorative and enjoyable to use.
