On the down side, when swung around, the balls get tangled up, and it can be difficult to untangle them. Additionally, the alignment seems slightly off, and the perpetual motion stops in less than a minute.The collision with the clacking sound keeps the kids entertained, almost mesmerized by it. At least until they start fighting over who is going to swing them. It's a decent size, and the base is stable enough to hold it in place, plus it's sturdy enough to handle small children fighting over it. the base is a heavy wood particulate, the bars and balls steel, and the lines are a filament like fishing line, welded between into the bar and balls. To assemble it, you just slide the bar ends into the holes in the base, just make sure they're fully seated. ### ⭐⭐⭐⭐ Pretty good *by A***R on Reviewed in the United States on August 11, 2021* From time to time it would get tangled up but I sure do like the motion ### ⭐⭐ Cheap packaging and generally cheap product *by A***R on Reviewed in the United States on February 22, 2017* When I took it out of the box one of the strings was detached from the silver plastic bar. You could tell it was really cheap packaging and the structure itself seemed pretty cheap as well, all plastic with just some fish line suspending the metal balls. Also the broken string was on the ball second from the right, so it kind of disabled the whole thing and I couldn't reattach it with superglue and I ended up throwing it out. I think if the packaging had been given a bit more thought and care the line might not have broken. Otherwise I'm sure the actual device would have been fine, just disappointing because I was so excited to get it only for it to be broken before I could use it. --- ## 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.lk/products/1453132-blastcase-newtons-cradle-art-in-motion-7-1-4-inch](https://www.desertcart.lk/products/1453132-blastcase-newtons-cradle-art-in-motion-7-1-4-inch) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-06-01*
