— 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 simulator with correct buoyancy physics, but it completely misses the prompt's core requirement: two crowns (pure gold vs. gilded), same mass, a vertical slider to lower them into water, and a Heureka moment — none of these features are present.
