The vaporized gas is pushed out of the fog machines in stage productions, nightclubs, or other special events. The liquid is propelled into a heat exchanger, where it is vaporized and then cooled and sent through a fan. The liquids commonly used in fog machines in water, mineral oil, glycerin, or propylene glycol.
