— 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
A well-built general Archimedes simulator with correct physics and live readouts, but it completely misses the brief: no crowns, no two-object comparison, no falling animation, no splash effects, no rising water level, no heureka moment, and uses a horizontal immersion-depth slider rather than the specified vertical crown-position slider.
