CO2 and Entertainment in Springfield and beyond12/10/2018Carbon dioxide (CO2) has been used in entertainment for a long time. The gas is cooled to a liquid to quickly (and economically) achieve special effects like fog and haze. Most have seen haze effects at concerts to emphasize a spotlight or on TV for cloud effects. Low-lying fog effects are achieved by using liquid CO2 that is typically stored in compressed cylinders. Low-lying fog is a result of the liquid CO2 being used to decrease the temperature on theatrical fog which then creates a thicker fog that stays very low to the ground. Fog can also be achieved inexpensively by using dry ice. Technicians are able to boil water in large containers 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 blow that gas into the desired direction for the fog effects. Liquid CO2 by itself can be used as an atmospheric fog in place of pyrotechnics in Springfield. This can be done by releasing 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 the result. This method of fog creation is frequently used in magic acts since the CO2 vapor quickly dissolves once the solenoid valve is closed. The entertainment industry not only consumes copious amounts of CO2, but makes high levels of carbon emissions as well. This is due 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 cut carbon emissions on various film and TV production sets.
