— 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 well-built general Archimedes demo but completely misses the prompt spec: no crowns, no crown comparison, no vertical slider, no falling animation, no Heureka moment, and no rising water level — it's a generic buoyancy sandbox with horizontal sliders and a single generic object.
