Dry ice is a "brrr-y" interesting form of carbon dioxide. Carbon dioxide is a gas that has no taste, smell or color. It's in the air you breathe and the fizzy bubbles you swallow when you drink soda pop, says 3-2-1 Contact magazine.
Carbon dioxide gas can also be cooled and squashed to form a solid. This ice is "dry" because it doesn't melt into a liquid. Instead, it turns directly into a gas.Dry ice keeps large amounts of medicine and food cold without making messy puddles. It also makes the eerie fog you might see drifting across the stage at a play or rock concert.
But don't grab a chunk of dry ice to be cool. Regular ice freezes at temperatures below 32 degrees Fahrenheit. Dry ice checks in at -109.3 degrees Fahrenheit. That's almost as chilly as a winter night at the South Pole - and cold enough to give you a bad case of frostbite!
