Chrome Newton's Cradle Physics Simulation

An interactive Newton's cradle built as a single-file HTML page with Three.js. Five polished stainless-steel balls hang between two chrome frames against a warm ivory studio backdrop, with softbox reflections that give it a luxury product-photography feel. Collisions carry momentum correctly through the chain, with 1-ball and 2-ball modes, slow motion, and playback controls. About 24 seconds. The recording is a side-by-side comparison with Astra 6 on the same subject, useful as a reference for physics explainers and short product-texture films.
