— 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 simulator with correct physics and live values, but fundamentally misses the prompt: no two crowns, no crown-specific narrative, no vertical dip-slider, no Heureka animation, no splash effects, no rising water level, and uses a dark background — essentially a wrong demo.
