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.
