— Two crowns — Same mass, different density — Vertical slider — Slider works — Slider controls crowns — Slider direction correct — Full slider range — Fall animation ✓ Water displacement ✓ Rising water level — Splash effects — Physics correct — Live mass value — Live volume value — Live density value — Live displaced water — Gilded displaces more — Heureka animation ✓ No external deps ✓ Light bg / dark text ✓ Self-contained HTML
Implements a generic Archimedes buoyancy demo with lead/wood blocks and button-triggered animations, but entirely omits the two-crown scenario, vertical slider, mass/volume/density/displaced-water live readouts, splash effects, and Heureka animation required by the prompt.
