The balls and the ball holder is made of stainless steel. Works perfectly for me and looks like it will last long. **Q: Does it go on forever? Or like an hour?** A: An hour! You're an optimist. This thing is horrible. It goes for about 15 seconds. I'm returning it. I remember these things from way back when and they would go for much longer. I'd gladly spend twice as much for one that was decent, but this is a waste of time. **Q: what are the stings made of?** A: They appear to be nylon fishing line **Q: I am purchasing these for a hotel and need 420 units - what is availability?** A: As of 7 14 2023, we have over 700 pieces in stock ready to ship via Amazon. ## Frequently Bought Together - PowerTRC Newtons Cradle Balance Balls 7 1/4" | Science Physics Gadget | Desk Toys & Accessories - ScienceGeek Kinetic Art Asteroid - Electronic Perpetual Motion Desk Toy Home Decoration --- ## 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.com.kw/products/333599235-powertrc-newtons-cradle-balance-balls-7-1-4-inch](https://www.desertcart.com.kw/products/333599235-powertrc-newtons-cradle-balance-balls-7-1-4-inch) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
