Before I tell you how dry ice is made and what it is used for, let me tell you what dry ice is. And why it’s really cool! Dry ice is solid carbon dioxide. Dry ice is cool because unlike regular ice, it does not melt into a liquid after being left out for several hours. It goes through something called sublimation. Sublimation means that the particles of a solid do not pass through the liquid state because its particles have enough energy that they form into gas.
It is made by first filling up a high-pressure container with liquid carbon dioxide. It is then sealed tightly. After it is opened again, the liquid expands at high-speed. The evaporation of carbon dioxide then cools the excess of the liquid down to freezing point. It is now turned
