No, you aren't going to send these to the moon, but if you are careful you can show your students all about kinetic and potential energy. Small and can fit on your classroom desk. ### ⭐ Crap Product *by B***T on July 20, 2018* This just arrived used and scuffed. I set it up before I noticed but once I did, not only did I notice the scuffs, it tangled immediately when trying to use it. These are not finger print marks people, they are a true fading from the coating. Returning today. ### ⭐⭐⭐⭐⭐ This Newtons Cradle is the perfect size and made with very sturdy material *by P***R on November 2, 2017* This Newtons Cradle is the perfect size and made with very sturdy material. It is just as the description states. a really nice addition to my office desk. --- ## 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.vn/products/43223585-newtons-cradle-metal-balance-ball-black-wooden-base-stainless-steel](https://www.desertcart.vn/products/43223585-newtons-cradle-metal-balance-ball-black-wooden-base-stainless-steel) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
