— 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
Completely wrong topic — this is a generic buoyancy simulator with selectable materials, not the Archimedes crown experiment; there are no crowns, no vertical dip slider, no falling animation, no splash, no rising water level, and no Heureka moment.
