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.
