Abstract
A low lying fog simulator including a liquid carbon dioxide source and a cooler to be used with a smoke generating machine. The liquid carbon dioxide is forced through an expansion valve to provide a cold carbon dioxide gas pocket through which the smoke passes prior to being dispersed into the ambient. When dispersed into the ambient the cold smoke/carbon dioxide mixture falls toward a level near the earth's surface simulating a low lying fog.
