✓ 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 (min=0 at top = air, max=1000 at bottom = water, but HTML layout places "Luft" label above and "Wasser" below — the mapping is actually correct directionally, BUT the slider thumb moves left-to-right underneath rotation, meaning dragging down increases value which maps t=1=submerged; however the live mass/volume/density panels are static (hardcoded, not updating), buoyancy force units are wrong (cm³ treated as m³ causing values ~5×10⁻⁴ N instead of ~0.5 N), and only displaced water updates live while mass/volume/density are frozen.
