"Dry Ice is frozen carbon dioxide, a normal part of our earth's atmosphere. It is the gas that we exhale during breathing and the gas that plants use in photosynthesis. It is also the same gas commonly added to water to make soda water. Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature: -109.3°F or -78.5°C. Dry Ice is widely used because it is simple to convert to its frozen form and easy to handle using insulated gloves. Dry Ice changes directly from a solid to a gas -sublimation- in normal atmospheric conditions without going through a wet liquid stage." (Quoted with permission from dryiceInfo.com.)

It is OK to put Dry Ice into regular or alcoholic beverages for consumption. Use 2 to 4 pounds of food grade Dry Ice for each gallon of room temperature beverage. Use large pieces of Dry Ice not small pieces. The Dry Ice is heavier than ice and will sink to the bottom. Do not use any regular ice! The Dry Ice will do the cooling and must not be eaten or swallowed. Too much Dry Ice will freeze the beverage so have extra standing by. It will bubble and give off the most fog when the beverage is room temperature. Because the Dry Ice is CO2 it will slightly carbonate the beverage. When most of the Dry Ice has sublimated, it will surround itself with ice and float to the top. There is still a small piece of Dry Ice in the center of these ice pieces so do not serve or eat them. Carefully ladle the beverage into drinking glasses without any Dry Ice. Add regular ice to glasses for cooler drinks.
