What is the Recipe to Make Dry Ice?

This dry ice recipe has been in my family since the time of the Mayflower. Take a gymnasium full of carbon dioxide, then start to press the walls in and suck out all the heat. By the time you get the temperature down to negative 110 degrees Fahrenheit and down to about 12 inches by 12 inches by 4 inches it is officially Dry Ice. Now don’t tell anyone that this is the way to make dry ice.
