How to play
Tap it to turn the crystal on its block; drag to turn it yourself.
Notes
Alum is a mineral salt that people have used for centuries to clear muddy water, to fix dye in cloth and, as a crystal stick, to stop small shaving nicks from bleeding.
Tap it and the crystal is turned a quarter of the way round on its block. Drag around it to see the frosted, uneven faces and the dark stand it sits on.
