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 — HTML vertical range defaults to bottom=min/top=max so dragging down decreases depth value, contradicting the labeled intent; all physics values are correct (Gold 19.32 g/cm³, gilded 13.15 g/cm³, same 1000 g mass) and the ASCII art heureka overlay is a strong touch, but the water-rise character quantization is coarse and splash effects are text-only approximations.
