Visitors tap the Air Cannon and this act compresses the particles of air inside. When this happens, air inside the cannon looks for a way to relieve the pressure and rushes out the hole on the other side. The smaller the hole, the greater the pressure and the faster the compressed air must move through the hole - resulting in a quick blast of air. Aim the Air Cannon and have a blast.
