A fog machine is a device that produces a thick, atmospheric mist by vaporizing a special liquid. It is widely used in theaters, concerts, parties, and film productions to enhance lighting effects and create a mysterious or dramatic ambiance.

A fog machine works by heating a special fog fluid and turning it into a thick mist or smoke. This usually happens in one of the following ways:
How a fog machine works
Heating the fog fluid
The machine has a heating element that quickly warms up the fluid.
Once the fluid reaches the right temperature, it evaporates and is expelled through a nozzle.
When it comes into contact with cold air, the vapor condenses and forms a thick smoke cloud.
Types of fog machines
Traditional fog machines: Operate with a heating element and fog fluid.
Hazer (haze machines): Produce a fine, long-lasting mist for subtle lighting effects.
CO₂ or dry ice machines: Create low-lying fog by evaporating CO₂ or dry ice.
