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

Highly complete SVG-based implementation with correct physics (gold 19.3 g/cm³, gilded 13.0 g/cm³, same 1000g mass), live displaced-water readout, splash particles, rising water levels, and Heureka animation — minor flaw: mass/volume/density values in the data panels are static (not dynamically updated per submersion fraction), and the water-rise pixel scale is arbitrary rather than derived from stated cross-section area units.
