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.\u003c\/p\u003e\u003cdiv style=\"background:#fafafa;padding:20px;border-left:4px solid #8b7355;margin:20px 0;border-radius:4px\"\u003e\n\u003ch3 style=\"margin-top:0\"\u003eFree Personalization Included\u003c\/h3\u003e\n\u003cp style=\"margin:0\"\u003e\u003cstrong\u003eCharacter Limit:\u003c\/strong\u003e 25 characters\u003cbr\u003e\u003cstrong\u003eEngraving Location:\u003c\/strong\u003e Base\u003cbr\u003e\u003cstrong\u003eHow to Order:\u003c\/strong\u003e Add your engraving text in the note field on the cart page before placing your order\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv style=\"background:#fafafa;padding:20px;margin:20px 0;border-radius:4px\"\u003e\n\u003ch3 style=\"margin-top:0\"\u003e✨ Key Features\u003c\/h3\u003e\n\u003cul style=\"margin-bottom:0\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 Polished Stainless Steel Balls — More Mass, Deeper Click:\u003c\/strong\u003e Ten stainless steel balls, each polished to a mirror finish, suspended in precise alignment on fine steel wires.
