The ever-popular Halloween accessory, the gas formed during the sublimation* of dry ice, spews from this jack-o-lantern’s mouth as a misty gas during the haunted labs at Penn State University in 2012.
No messy drips; dry ice turns from a solid directly to a gas at room temperature.
When handling solid dry ice, protective gear must be worn.
[Thanks, subtlescienceandexactart for the correction. The process of a solid turning directly to gas is called sublimation, not evaporation. We stand corrected and we love learning, too.]
