Dry Ice Facts and Information:

What is Dry Ice?

Dry Ice is solid carbon dioxide (CO2). When you pressurize CO2 and then flash to 0 psig the temperature drops to -109.3 degrees Fahrenheit (or below), it becomes dry ice. Dry Ice has almost twice the cooling capacity of wet ice. Dry ice “sublimates” (goes from a solid to a gas) as it disappears. Due to this, it is important to store dry ice in a well-ventilated area.  Moving air sublimates dry ice. So, if you store it in a regular freezer, the fan that moves the air to cool it will end up making the dry ice evaporate faster. When dry ice comes into contact with a liquid, it liquefies before it becomes a gas, forming carbonic acid (carbonated water).

How to Freeze with Dry Ice

Step 1: Insulate dry ice with newspaper, cardboard, etc.

Step 2: Place dry ice at the bottom of the cooler. Then, add items to be frozen.

Step 3: Place dry ice on top. Then, close the cooler.

How to Chill with Dry Ice

Step 1: Insulate dry ice with newspaper, cardboard, etc.

Step 2: Place dry ice at the bottom of the cooler. Then, layer wet ice over dry ice.

Step 3: Add items to be chilled. Then, pour wet ice over top.

Shipping with Dry Ice

Department of Transportation (DOT) regulations apply to shipping foods with dry ice. Place dry ice on top of items to be kept frozen. If items only need to stay cold, place dry ice in bottom of cooler and place cardboard on top of the dry ice. Contact your shipper for details.

Halloween Fog Effect

To create the ideal long-lasting fog effect, use 1 lb. of ice per half gallon of water. For example, use 2 lbs. per 1 gallon of water. Submerge the dry ice in a bowl so that it is about ½” from the top of the bowl. Use a heavy plastic bowl that is 3 times as deep as the thickness of dry ice you’re using. Use a small fan to direct the fog. Cycle the water as often as possible with new warmer water to keep the effect going as long as possible.

Power Outages

If your power goes out use 1.5 lbs. or dry ice per cubic ft of refrigerator space per 24 hours.

Disposal of Dry Ice

Dry ice turns to gas naturally. Place any unused dry ice in a cooler, paper bag or outdoors. It will disappear in a short amount of time. Be sure that children or pets do not come into contact with dry ice.
