✓ 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 reads "LUFT↑ WASSER↓" but value=0 maps to crowns in air, meaning dragging down raises value which lowers crowns — semantically correct behavior but the label implies top=air/bottom=water while the HTML range input's visual top is max not min, so direction is browser-dependent and inconsistent); mass/volume/density are static labels not live-updating values, and the "dip percentage" used as immersion is a single shared t applied identically to both crowns rather than separate physics.
