CO2 and Entertainment in Riverside and beyond

Carbon dioxide (CO2) has been used to amplify special effects in the entertainment industry for a long time. The gas is chilled to a liquid to easily (and economically) create special effects like fog and haze. Many people have witnessed haze effects at concerts to highlight a spotlight or on TV for cloud effects.

Low-lying fog effects can be created by using liquid CO2 that is usually placed in compressed cylinders. Low-lying fog is one of the effects of the liquid CO2 being used to decrease the temperature on theatrical fog which results in a thicker fog that stays very low to the ground. Fog can also be created inexpensively by using dry ice. Technicians can heat water to boiling or near boiling temperatures in large vessels and then place 1-2 pieces of dry ice in those containers. Since carbon dioxide does not persist as a liquid in atmospheric pressure, it instantly becomes a gas. Usually there is a fan at the top of the container to push the CO2 into the desired direction for the fog effects.

Liquid CO2 alone can be used as an atmospheric fog in place of pyrotechnics in Riverside. This can be done by emitting liquid CO2 in the air by using an electric solenoid valve. When the CO2 becomes a vapor and condenses moisture in the air, large clouds of gas are created. Since the CO2 vapor disappears immediately once the valve is closed, magicians will use this type of fog creation.

The entertainment industry not only consumes copious amounts of CO2, but makes high levels of carbon emissions as well. This can be attributed to transportation, onsite generators and pyrotechnical effects that require the CO2 gas. Therefore the Producers Guild of America has created the Green Production Guide to reduce carbon emissions on various film and TV production sets.
