The CONCEPT SMOKE MEDIUM DISPERSING SMOKE is a specific product designation for a smoke fluid that produces a medium-duration smoke effect. It is used in professional stage and special effects equipment, often in conjunction with a fog or haze machine. The smoke will linger in the air for a moderate amount of time before dissipating. It's not a quick-dissipating "fast fog" and it's not a long-lingering "heavy smoke." This type of smoke is ideal for a variety of applications, such as concerts, theatrical productions, and film shoots, where a visible haze or cloud is needed for a sustained period without completely obscuring the scene.
