Slider direction is inverted (value=0 at top means crowns in air, but the HTML writing-mode/rtl CSS causes the physical top of the slider to render as "Wasser" visually); physics values are accurate (gold 19.32 g/cm³, gilded 3.7 g/cm³, same 1000 g mass), but both crowns submerge at identical rates rather than showing any buoyancy difference in behavior.
