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

Competent general Archimedes simulator with correct physics and live values, but fundamentally misses the prompt: no two crowns, no crown-specific narrative, no vertical dip-slider, no Heureka animation, no splash effects, no rising water level, and uses a dark background — essentially a wrong demo.
