Using Dry Ice to Create Fog Using Dry Ice to Create Fog

What You'll Need
3 buckets
A kettle
Protective eyewear
Protective gloves
20 pounds of dry ice
A fan

Artificial fog is typically made using dry ice. Dry ice is a solid form of carbon dioxide. It produces foggy vapors when water is poured over it. The more dry ice you use, the greater the amount of fog you are able to create. Dry ice has a temperature of minus 109 degrees Fahrenheit, and can be extremely dangerous to handle. Exposure to solid dry ice can cause frostbite. It also poses asphyxiation dangers, and should be used in well ventilated areas. You will need to use special care in handling and using your dry ice.

Step 1 – Safety

Be sure to put on your protective eyewear and gloves before you begin to work with the dry ice, to protect yourself from any accidental burns. Keep the buckets of dry ice in a location that is out of the way, to prevent anyone else from becoming accidentally injured. Purchase your dry ice on the day you are using it. Be sure to purchase a food grade product. The temperature of the dry ice will force your freezer to shut down. It is better to store the material in an ice chest. In the ice chest, the dry ice will reduce by about 10 percent.

Step 2 – Preparing the Buckets

Position 2 of your buckets in the room where you want to create your fog. The buckets should hold at least 10 gallons. Be sure the buckets are positioned well apart, so that the fog will fill the entire space.

Step 3 – Creating the Fog

Carefully place 10 pounds of your dry ice to the 2 buckets. Heat 5 gallons of water in a large pot on the stove. If necessary, use a kettle to heat the water, but do not let the water get to the boiling point. Pour the hot water into your third bucket. Carefully carry the bucket of hot water over to 1 of the buckets containing dry ice. Pour some of the hot water over the ice, until it is completely covered. Continue over to the second bucket of dry ice, and pour the hot water over it as well. The fog will begin to develop and should last for about an hour.

Step 4 – Circulating the Fog

Use an oscillating fan to circulate the fog throughout the room, and produce a rolling fog look. Keep the fan away from the water. Turn the power switch on the fan to the on position. Set the fan level to low. Press the oscillating button, to enable the fan to rotate automatically. The fan will force the fog to move about the space.

Step 5 – Disposing of the Dry Ice

Put on your protective work gloves and eyewear. Place the used dry ice into a plastic container. Place the container in a well ventilated space, to prevent a buildup of carbon dioxide. Preferably, use a safe, outdoor location. Keep all humans and animals away from the container. Allow the ice enough time to evaporate into the air. Never flush or dump the dry ice down the drain, in any way. Never place the dry ice in any confined areas.
