— 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 buoyancy simulator but fundamentally misses the prompt entirely — no crowns (pure gold vs. gilded), no same-mass comparison, no vertical submersion slider, no fall/splash animation, and no Heureka moment; it instead offers material-selection and density/size sliders for an arbitrary generic object.
