Slider direction is inverted (min=0 labeled LUFT at top, max=100 labeled WASSER at bottom, but the HTML slider's thumb starts at top for value=0 which maps to air — actually direction may be correct visually due to CSS rotation, but the rotate(-90deg) transform makes left=bottom and right=top, so dragging "down" increases value and submerges crowns, which is correct directionally; however the ASCII water-level rise formula uses a crude fixed divisor (18.0) rather than proper tank-area scaling, and buoyancy is reported in mN but computed as cm³×g/cm³×9.81 = grams·cm/s² which is actually dynes, not mN — a unit error.
