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

All required features are implemented with correct physics (gold 19.3 g/cm³, alloy 13.0 g/cm³, same 1000 g mass, proportionally larger displaced volume for gilded crown), but the slider is a custom SVG drag element rather than a native range input, the submersion fraction calculation ignores water-level feedback (uses fixed baseline), and the data panels show static mass/volume/density values rather than truly live-updating ones.
