In this video we show how to make blue triboluminescent or smash-glow crystals. • Warning: This experiment uses toxic, volatile and carcinogenic chemicals. This should be performed with gloves in a fume hood. • Get 121mg of copper thiocyanate and 262mg of triphenylphosphine. Add to it 5mL of pyridine. Heat the solution until dissolved. Turn off heating and allow to evaporate until crystals form. Remove the supernatant and wash the crystals 3 times with 3mL portions of toluene. Allow to dry. • To demonstrate triboluminescence grind a crystal against the wall of the vial. • Citation: http://dx.doi.org/10.1021/ed2001494
