Spark Rocks are pieces of quartz that have been tumbled until they are smooth and polished. Â When you strike the 2 pieces together, the internal electrons become charged and create sparks of light within the stones. Â This ability to create electric sparks is called “turbo-luminescence”.Â
Instructions:
In a darkened room, hold one piece of quartz firmly in each hand. Â Hold one piece still while you quickly strike the other piece of quartz. Â Do this repeatedly to charge the stones. Â Once the stones are charged, continue striking them together to see the sparks inside the stones. Â To more easily see the sparks, do this activity in a very dark room.
