It is like a crystal wine glass. You dip your finger in the wine to get it moist then glide it along the rim slowly as you listen to the pitch of the glass and the vibrations build under the administration of your digit. It slowly grows in volume. The crystal shudders more intensly with each rotation until finally the lattices within can no longer remain bonded. The intense energy finally tears the molecules apart and the once stoic glass shatters into tens of thousands of tiny shards.
