Flexi Says: Dry ice is solid carbon dioxide. It is usually made by first liquefying carbon dioxide under high pressure and then injecting the liquid into a mold and freezing it at a temperature of -78.3 °C (-109 °F). Under normal atmospheric temperatures and pressures, the dry ice will turn from solid directly into gas in a process called sublimation. It is called "dry" because it doesn't melt into a liquid and thus never becomes wet.
