About This Item
Ten polished stainless steel balls suspended on fine steel wires from a stainless steel frame, mounted on a solid black wood base. Pull one ball back and release—the momentum transfers through the row and the opposite ball swings out to the same height, returns, and the cycle repeats. Ten balls means more visual mass in motion, a deeper click on impact, and a longer swing cycle before friction brings it to rest. No batteries. No motor. No power source. Just conservation of momentum, playing out on your desk. Comes in a gift box. Free engraving on the base—up to 25 characters.

✨ Key Features
- 10 Polished Stainless Steel Balls — More Mass, Deeper Click: Ten stainless steel balls, each polished to a mirror finish, suspended in precise alignment on fine steel wires. Ten balls means more visual mass in motion compared to a standard 5-ball cradle—a fuller swing arc, a deeper impact sound, and a more dramatic momentum transfer to watch.
- Stainless Steel Frame + Solid Black Wood Base: The frame is stainless steel—clean, modern, and corrosion-resistant. The base is solid black wood—substantial, stable, and weighted to keep the cradle in place during operation. The combination of chrome steel and black wood gives the piece a modern, executive desk aesthetic.
- Perpetual Motion — No Batteries, No Power: Pull one ball back and release. The momentum transfers through the row—the opposite ball swings out to the same height, returns, and the cycle repeats. No batteries, no charging, no power source. Conservation of momentum and elastic collision do the work.
- Large Format — 37 × 20 × 24cm: At 37cm wide and 24cm tall, this is a statement desk piece—large enough to command attention on a desk or shelf without being impractical. The 20cm depth gives the swing arc room to move freely.
- Gift Box Included: Comes packaged in a gift box—ready to give without additional wrapping.
- Free Engraving (Up to 25 Characters): Engraved on the base before shipping.
