— 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 buoyancy demo with a single blob object and a horizontal mass slider — it has no crowns, no vertical slider, no water-level rise, no splash, no density/volume/displaced-water readouts, and no Heureka animation, making it almost entirely off-spec for the Archimedes crown visualization prompt.
