— 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
Generic Archimedes buoyancy simulator with good physics and live readouts, but completely missing the two-crown (pure gold vs. gilded) narrative, vertical slider, fall/splash animations, rising water level, and Heureka moment that the prompt specifically required.
