✓ 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 is horizontal (not vertical) and its direction is inverted (left=air, right=water maps to min=0→max=100, but the label reads "Luft ← → Wasser" suggesting left-to-right, which is not the required top=air/bottom=water vertical orientation); physics values are sound (gold 19.32 g/cm³, gilded 11.00 g/cm³, same 1000g mass), Heureka animation and splash effects are well-implemented, but there is no true fall/drop animation between air and water.
