✓ 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 top=Luft/air but the CSS rotates a horizontal range input -90deg making slider bottom visually correspond to higher values/water, while physically the slider thumb at top maps to value=0/air and bottom to value=100/water — the visual label placement is correct but the rotated input's drag direction is counterintuitive/inverted); physics values are solid (Au 19.32 g/cm³, Au+Ag 13.5 g/cm³, same 1000g mass), all live data panels, splash, ripple, bubble, and Heureka effects are well-implemented.
