✓ 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 maps to crowns in air at top, but HTML vertical-lr+rtl slider means dragging down increases value → water, which may be correct visually, but the label reads "▲ LUFT WASSER ▼" suggesting top=air is intended — needs verification; live mass/volume/density values are static (hardcoded in HTML, not dynamically updated per immersion state), so only displaced water is truly "live".
