✓ 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/Luft at top maps to air correctly in label but slider HTML orientation means dragging up increases value toward water, not air-to-water top-to-bottom as expected); mass/volume/density panels show static hardcoded text rather than live updating values, so live_value_mass/volume/density are false; no discrete fall animation (crown moves linearly with slider, not a triggered drop); physics values (19.3 vs 13.0 g/cm³, same 1000g mass) are plausible and displacement difference is visually shown.
