Answer: Dry ice is the common name for the solid form of carbon dioxide. Originally the term ' dry ice ' was a trademark for the solid carbon dioxide produced by Prest Air Devices (1925), but now it refers to any solid carbon dioxide. Carbon dioxide is a natural component of air.Dry ice is safe to use for smoke machines and lab experiments, providing care is taken to avoid frostbite.ry ice is made by compressing carbon dioxide gas until it liquefies, which is at about 870 pounds per square inch of pressure at room temperature.
