Triboluminescence in crystals is the emission of light from a substance caused by rubbing, scratching, or similar frictional contact.

If you do have crystals;

You will need;

  • Two Milky Quartz crystals
  • A completely dark room

Take your crystals into a darkened room and stand in the dark. Hold one piece of quartz in your left hand and the other piece in your right hand.

Firmly press the the two pieces together and with pressure drag one against the other as if you were striking a match.

If you do this properly and if you have pieces of quartz that are triboluminescent, you will see a brief flash of light that penetrates deeply into the translucent quartz.

If you don’t have crystals;

Have you ever wanted to see a crystal glow but you don’t have access to a full stock of them? Than here’s a way that you can view your own glowing crystal.

You will need:

  • Sugar Cubes or Polo Mints
  • A heavy bottomed glass
  • A completely dark room

The first step should ONLY be carried out by an adult and with extreme caution.

When you’re in the dark room place the polo mint or sugar cube on a hard surface and smash it with the bottom of the glass. You should be able to see a faint blue glow that emanates from the sugar cube, this is triboluminescence.

The 17th century polymath Francis Bacon discovered this effect. It was later recorded by Robert Boyle who observed that ‘hard sugar being nimbly scraped with a knife would afford a sparkling light’.

Disclaimer – Please use extreme caution when using a glass in the above method. I cannot be held responsible for those that dont know they’re own strength!
