This Prolight Mr Kool low fog machine creates a low-lying fog thats stays close to the ground, very similar to a dry ice effect. Using standard fog fluid and ice cubes, with no need for additional chilling or expensive fluids. The fog passes through the cool ice box, increases in density and then sinks, to imitate the effect caused by dry ice. Mr kool can be raised high for a waterfall style effect, or left on the floor for the lower density fog to gives a dramatic covering effect.
