A coffee cup of dry ice.

"Dry Ice was invented in 1835 by Adrien Jean Pierre Thilorier who invented an Ice substance". In Adrien's observations, he opened a cylinder that had CO2, and most of the Co2 disappeared. Through the observation, it had left dry ice in a solid state, in the container. Today, Dry Ice is used for many things like medicine, keeping food at a safe temperature, and even for getting rid of bugs. Also, Dry Ice is used to contain elements that need to remain cold, for example: Ice Cream. Dry Ice can even be used to make Ice Cream! Today, people can open a valve of a gas pipe and study the gas cloud that comes out with a part of it turning into dry ice snow flakes. Adrien was the first person to form the dry Ice industry.

"Dry Ice Corporation of America teamed up with Liquid Carbonic in 1929 to build 17 dry ice manufacturing plants across the US including Los Angeles, California. Before the plants were finished DryIce Corporation and Liquid Carbonic dissolved their agreement and went their separate ways becoming competitors. Birdseye Frozen Foods started in 1931 and immediately used dry ice for transporting their samples to promote their products. By 1932 with six or seven other manufacturers of dry ice, the estimated US production was 120,000,000 pounds

Today there are thousand of dry ice producers all around the world. Many sell to the public, but many also manufacture dry ice for their own use such as Disney Land"
