About This Item
Ten mirror-polished stainless steel balls suspended on fine steel wires from a stainless steel frame, set on a solid black wood base. 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. Ten balls deliver more visual mass in motion and a fuller swing arc than a standard five-ball cradle. No batteries. No motor. No power source. Just conservation of momentum, playing out on your desk.

FAQ
Why does the opposite ball swing to the same height?
Conservation of momentum and energy: the impulse transfers through the aligned row, and the last ball swings out to nearly the same height, repeating until friction slows it.
Does it need batteries or a motor?
No — it runs entirely on mechanical momentum.
How is 10-ball different from 5-ball?
Ten balls add more visual mass in motion and a fuller swing arc before it comes to rest.
