مهد نيوتن من Australian Geographic - قاعدة سوداء

The clack of the balls against each other is crisp and clean, which makes it oddly hypnotic to watch while I'm on calls. It’s a solid, weighty piece that sits perfectly on my desk and genuinely demonstrates momentum just as described.

The stainless steel balls have a satisfying weight to them, and the black base looks really sleek on my desk. Watching the momentum transfer never gets old, and it's held up well after a month of daily fidgeting.

I've had this on my desk for a week and it's surprisingly calming to watch the momentum transfer between the polished steel balls. The base feels solid and heavy enough that it doesn't slide around when I nudge it.
