When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward. Newton's Laws of Motion: "For every action there is an equal and opposite re-action." Fine argument of Newton's law of motion and the starting point of physics. Inspired us to better understand the concept of conservation of momentum. Demonstrates Conservation of mechanical energy. Newton Cradle will never be outdated. It's great for physical teachers, students, office workers, kids, men and women at all ages.

Difficult to put together, tacky and uneven. Extremely disappointing. I really SHOULD read reviews before buying. The motion only lasts about 10 seconds too (see video). Pay more on a bigger sturdier product is my advice ### ⭐⭐⭐⭐⭐ Remember the physics lessons *by R***A on 1 August 2019* I bought this to give it as a gift to my managerThis is quite unique idea that remember your physics lessons. Good to have it in your office table. ### ⭐ the only reason i haven't returned is because i just ... *by B***A on 13 July 2018* the only reason i haven't returned is because i just thrown it away. Couldn't put the bars in the frame , the bars didn't fit into the frame and all the balls got tangled. small and cheap material. --- ## 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.sn/products/173816075-meyall-newtons-cradle-balance-balls-art-in-motion-toys-kids](https://www.desertcart.sn/products/173816075-meyall-newtons-cradle-balance-balls-art-in-motion-toys-kids) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-26*
