What is dry ice?
Dry ice is pure, solid carbon dioxide (CO2). As a gas, CO2 exists naturally in our environment. It’s called “dry ice” because it does not melt. Dry ice goes directly from a solid to a gas in a process called sublimation. Dry ice keeps items colder for much longer than traditional wet ice because dry ice is extremely cold, -109 degrees F (-78.5° C). Dry ice sublimates into carbon dioxide gas instead of melting, leaving no liquid mess to clean up which is why dry ice blasting is a popular and environmentally friendly way to clean.
