— 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
Competent general Archimedes demo with correct physics readouts and bubble effects, but fundamentally wrong subject — implements a single configurable block in a tank rather than the two-crown (pure gold vs. gilded) Archimedes scenario, with no vertical crown-dipping slider, no two crowns, no crown fall/splash animation, no rising water level, and a dark background instead of the required light one.
