— 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
This is a generic Archimedes buoyancy simulator for arbitrary materials — it completely ignores the Archimedes/crown narrative: no two crowns, no gold vs. gilded comparison, no vertical slider, no fall animation, no rising water level, and no Heureka moment.
