A device designed to generate dense vapor, often resembling smoke or fog, typically for theatrical productions, concerts, or special effects. This artificial haze is created using various methods, including vaporizing specialized fluids or using dry ice. A simple example would be a fog machine utilizing a glycol-based fluid heated and then rapidly cooled to create a thick, white plume.
The ability to control atmosphere enhances the visual impact of lighting and laser effects, creating a more immersive and engaging experience for audiences. Historically, atmospheric effects in theater relied on less sophisticated methods like burning incense or releasing steam. Modern technology allows for precise control over the density, duration, and even color of the generated vapor, expanding creative possibilities in entertainment and other fields like fire safety training.
