How Do They Make Fog in Movies?
Special effects teams employ various techniques to create realistic fog in movies, utilizing specialized equipment and materials. One common method involves using a fog machine that injects “fog juice” into the air.
This mixture, typically composed of glycerin and water, mimics the behavior of natural fog, which gradually dissipates over time. The process begins with the preparation of the fog juice, a standardized blend of glycerin and water.
Once prepared, the solution is pumped through a super-heated nozzle at high pressure, creating a fine mist that disperses evenly throughout the desired area. The resulting fog can be tailored to achieve varying levels of density and duration, depending on the specific requirements of the scene.
