About This Item
Five polished chrome steel balls suspended on fine steel wires from a chrome rectangular frame. Pull one ball back and release — the momentum transfers through the row, the opposite ball swings out, then back, then out again. Continuous, hypnotic, and governed entirely by physics. The balls hang in perfect alignment — each touching the next, each wire tensioned to the same length — and that alignment is what makes the momentum transfer clean and precise. No batteries. No motor. A classic desk piece for office openings and housewarmings alike.
