— 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
Completely wrong concept — implements a generic drag-and-drop buoyancy demo with a cube/sphere (no crowns, no slider, no mass/volume/density values, no Eureka moment), missing virtually every required feature of the Archimedes crown experiment.
