— 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
This is a general-purpose Archimedes buoyancy demo with no crowns, no vertical slider for crown dipping, no two-crown comparison, no Heureka animation, and no splash effects — it completely misses the Archimedes crown-experiment prompt despite having solid buoyancy physics and animation for a generic object.
