✓ 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
Mass/volume/density values are hardcoded (not live), the crown's submerged fraction uses a crude geometric heuristic that doesn't track submersion proportionally to volume, and the water-rise calculation uses arbitrary scaling factors rather than true Archimedes math, making the physics display misleading despite correct qualitative direction.
