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/top maps to AIR which is visually correct but the HTML rotates a horizontal range -90deg making top=low-value=AIR — actually the label says LUFT at top and WASSER at bottom, but the CSS rotates the slider so dragging down increases value toward 1000, which should move crowns into water; however the visual labels on the container place LUFT at top and WASSER at bottom but the rotated slider's thumb at min sits at the bottom visually, making top=WATER/bottom=AIR — direction inverted); mass, volume, and density values are static (hardcoded in HTML, not updated live via JS), so live_value_mass/volume/density are false.
