— 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 demo with a single cube and a horizontal slider — it has no crowns, no mass/volume/density/displaced-water readouts, no vertical slider, no water-level rise, no splash effects, and no Heureka moment, missing virtually every prompt-specific requirement.
