— 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 a generic single-object Archimedes demo with no crowns, no slider, no density display, broken physics (weight hardcoded at 80 N while buoyancy calculates to ~0.78 N for 80 cm³), and is missing nearly every required feature of the prompt.
