✓ 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
Slider direction is inverted (label says Luft→Wasser top-to-bottom, but the horizontal range input rotated -90° maps min=left=bottom=air to max=right=top=water, making top of the visual slider mean water, not air); all other physics, data display, splash, wave, and Heureka features are well-implemented.
