Inside a theatrical haze machine. (hazer)

While Cara was fixing this machine I decided to take a look at what was inside. These units are similar to smoke machines that produce a smoke like effect with a fog of glycol droplets split apart by the sudden boiling of the water in the fluid. The main difference is that hazers use a strong air flow to diffuse the fog into the air quickly and create a light enhancing haze. In this case an air pump is being used to push droplets of the haze fluid through the heater coil to give a reduced output of fog from a large gauge heated vaporisation tube.
