— 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
Implements generic Archimedes buoyancy with ASCII art and static buttons, but completely omits every required feature: no crowns, no vertical slider, no falling animation, no water level rise, no live physics values, and no Heureka moment.
