  1. FYI, sugar is triboluminescent too. Take some large sugar crystals, turn out the lights, and smash with a hammer. You should see some very faint purple light. Wintogreen lifesavers have an even more dramatic effect.

  2. I vaguely recall an old “chemistry experiment” book that claimed you could produce glow-in-the-dark paint by roasting together sulfur and Oyster Shells (Calcium Carbonate.) Apparently whatever doping ingredient was needed was already present in the oyster shells…
