— 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 general Archimedes buoyancy simulator with a single draggable sphere and density/fluid sliders, but is entirely missing the core prompt requirements: no two crowns, no same-mass/different-density comparison, no vertical submersion slider, no crown fall animation, no rising water level, no splash effects, no Heureka animation, and uses a dark background.
