How does it work dry ice?

A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid. read more

Dry ice also has the very nice feature of sublimation-- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid. The super-cold temperature and the sublimation feature make dry ice great for refrigeration. read more

Unlike the ice cubes in a cold drink, dry ice doesn't melt to become liquid at all. Instead, at room temperature, it changes directly from a solid to a gas a process called sublimation. read more
