How to make dry ice?

Expert Answer:

The carbon dioxide gas is pressurized and cooled to form liquid CO2. Then liquid carbon dioxide is injected into either a block press or pelletizer. These machines have chambers in which, once released to atmospheric pressure, the liquid carbon dioxide converts to dry ice snow and carbon dioxide gas.
