Did you know?
- Anhydrite means without water in Greek: it is like gypsum, but with no water built into its crystals.
- When anhydrite absorbs water it turns into gypsum and swells, which can lift tunnel floors and crack buildings.
Could you guess it from clues?
WildGuessr picks a secret animal, plant, fungus, stone, prehistoric creature or space object and you ask yes-or-no questions about it, such as its group or where it grows. The fewer clues you need, the more points you score.
