Abstract: A method for producing low lying fog as a special effect, for example in stagecraft, comprises the step of enriching the fog that emerges from a fog machine with water. The fog is wetted with water, mixed and approximately saturated. For this purpose, finely atomized water having a droplet size of 2? to 10? can be used. A corresponding device comprises a mixing zone (6), in particular a mixing chamber (7, 13, 20) connected to the fog machine (1), and a fan (2, 11, 19) having a downstream atomizer (3, 12, 18), e.g. an ultrasonic atomizer for water. The fog is mixed with the enriched air stream, if necessary in a counter-current, and reaches the open air as a heavy low lying fog via a water separator (14) and possibly a cooling unit (17).
