Sofia U. ★★★★★ Oct 22, 2026

The battery-powered swing means it keeps moving long after I’ve stopped pushing, which is oddly calming during conference calls. The gentle clack of the spheres is the perfect white noise backdrop.

Got this for my desk to fidget with during calls, and the endless swinging really does make gravity feel like magic. It's quiet enough that it doesn't bother anyone on the other end of the line, and the gentle push keeps it going for as long as I'm working.

I was skeptical about a battery-powered Newton's Cradle, but the way it keeps the motion going with just a tiny push is surprisingly hypnotic. It's perfect for my desk when I need a quick mental break from work.
