— 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 single-object buoyancy demo (density slider on a sphere) with no crowns, no dual-crown comparison, no vertical slider, no water-level rise, no splash, and no Heureka animation — the Archimedes crown experiment is almost entirely unimplemented.
