CERROPI Large Newtons Cradle Pendulum with 7 Balls, Physics Perpetual Motion Desk Toys for Office, Calm Down Fidgets, 50+ Sec Swingtime (Beech Base)

Excellent quality and packaging protected it. I bought this for the conceptual Physics class in our home school curriculum. The kids love it. Highly recommended.

After reading reviews of other Newton’s Cradles, it seems like a common problem is that the balls don’t swing back & forth for very long. This cradle however, does not have that problem, as it goes for about a minute & a half with one release. I’m guessing the 7-balls (vs most cradle’s 5 balls) makes a difference. We got the wood base model and are very pleased with it’s sturdy quality and it’s simple but attractive look. Take note, do not release the first ball from too high otherwise the balls/strings can get tangled, which can very easily and quickly dissolve into a knotted mess. Fortunately, the customer service at CERROPI is proving to be fantastic bc my son did, indeed, release from too high and the balls got tangled. CERROPI support immediately responded and tried to help me fix it myself but then quickly offered a replacement (I wouldn’t recommend counting-on the same outcome if your balls/strings get tangled). As someone who feels like decent, let alone fantastic customer support is a very rare thing these days, I am very pleased and grateful for the response I got from CERROPI. I would DEFINITELY recommend this Newton’s Cradle for anyone looking for one. I was hesitant to spend a little more bc there are definitely less-expensive ones out there, but I doubt the quality is nearly as good with the cheaper ones, and I’m very glad I spent the extra money to get this high-quality cradle, not a cheap, plastic one.

It arrived in perfect condition and its just great ,looks good sitting on my sons desk , it was his birthday present

It is a quality item but wish the swinging motion would last a bit longer. Other than that, it swings at a good speed and it can be calming while working.

My grandparents had one of these when I was a kid and now I'm able to share this one with my grandson. I love the wood aesthetic. It's a pretty knick knack to have around. It's a little pricey, but after reading reviews of cheaper ones I decided to go with more expensive. It's definitely worth paying more for good quality. What I didn't appreciate was getting an email about infant sleep safety as a result of this purchase. Just because the product name has the word 'cradle' in it, does not make it an infants sleeping place. Can we do away with the AI purchase police?

This accomplished what I wanted for my office. A conversation started that can break the ice during meetings. It works as described, and it was very easy to assemble. It is not a heavy weight pendulum that will continue in motion once it is started which is little disappointing. But it will continue for a good 3-4 minutes before it loses all momentum. If you are wanting something that draws peoples attention then his is perfect. If you are wanting something more scientifically accurate, this is not a purchase for you.

LOVE IT

Securely packed in four sided foam. Fun to have on desk. The motion lasts 50” -ish.

Well built good looking cradle fulfilled Grandson's wish looks great on his desk

Purchased for my grandson and it was perfect. Arrived within 4 days and he is fascinated by it!

The website has the words "made in Japan" to suggest that it is a high quality product, made with precision and care. I therefore purchased it as a gift with this expectation. It arrived and has on the box "Made in China"

A quality product. Built for creating scientific curiosity (in my grandson😉). Should last for a good time. Performs as advertised.
