✓ 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 (top label = "Luft/Air", slider starts at 0 = air, but the vertical range input with direction:rtl likely renders with 0 at bottom and 100 at top in most browsers, making top=water/bottom=air); ASCII art approach is creative and all live physics values, water rise, splash effects, and Heureka overlay are genuinely implemented.
