When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward. The last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction. The device is named after 17th-century English scientist Sir Isaac Newton. It is also known as Newton's Balls or Executive Ball Clicker.Package included: 1 x Newton's Cradle Size: L:7.1x4.7x7.1 inch Weight：2.5Ib (Include Packing Box) Features: Demonstrates Conservation of mechanical energy Intelligence Development: Fine argument of Newton's law of motion and the starting point of physics.( Newton's Laws of Motion ). For every action there is an equal and opposite re-action.Inspired us to better understand the concept of conservation of momentum.

Windex made the mirror and base look like new which is what I had expected to see.Must be assembled by an adult or a resourceful teen.To fully seat the 4 corners posts I had to lightly tap them in place with a hammer over a folded cloth to protect the chrome. Would be very difficult to ever disassemble.If all four posts are not fully seated, the balls will will not strike each other in alignment.Once assembled properly this Newton's Cradle is rock steady.The tall side posts and sturdy wooden base provide for really good clickity-clack action.Would buy this item again. ### ⭐⭐⭐⭐ Good quality *by H***I on Reviewed in the United States on October 24, 2020* I looked at a lot of reviews and settled on this one. It was the big gift my child wanted for his birthday. It was a little bit difficult for me to set up- my husband had to push the poles in. The quality is fine, the bowls and wire is good but the two signs do tilt towards the middle for us. I think it could be engineered better, perhaps with bigger holes and rubber at the ends of the poles to stick into the holes for a good snug fit. If it breaks a few months from now, I would probably re-order this one again. ### ⭐⭐⭐⭐ Good for the value paid *by Z***N on Reviewed in the United States on June 4, 2020* It was a gift to my husband for his new office. Although he loved it, I have to give 1 star less because the poles were a bit loose. The poles didn’t fit right into the corner holes, the heavy balls keep pulling the poles to the center and have to be readjusted constantly. Overall a good value for the money. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/30813905-xch-robots-newtons-cradle-5-pendulum-balls-big-newtons-cradle](https://www.desertcart.pl/products/30813905-xch-robots-newtons-cradle-5-pendulum-balls-big-newtons-cradle) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-02*
