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 maps to crowns in air which is semantically correct per code, but the CSS uses `transform: rotate(-90deg)` on a horizontal range, meaning visually dragging down increases value — however, value=0 is air and value=1000 is submerged, so top of physical slider = low value = air, which is actually correct; that said the gilded crown visually displaces more water as required, all physics values are plausible, and the heureka overlay triggers properly at full submersion.
