— 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 principle demo (density/volume/fluid sliders, live force values, force arrows) but completely misses the prompt's specific requirements: no two crowns, no Hiero/Archimedes story context, no vertical slider controlling crown submersion depth, no fall or splash animation, no rising water level, no Heureka moment, and uses a dark background rather than light.
