Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H 2 CO 3). [1]
Vanilla Ice was onto something in 1990 when he rapped, “Ice, ice baby.” The USDA confirms that nearly every food— except eggs in shells and canned foods— can be frozen.
In Utah, simple possession of a dry ice bomb or similar pressurized chemical reaction bomb is a second-degree felony. [16] In Colorado, the creation of a dry ice bomb is considered illegal due to interpretation as "possession of an explosive device" [citation needed] Leaving an unexploded dry ice bomb can be construed as public endangerment.
Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.

Freeze-dried strawberries. Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2]
Freezing keeps food safe to eat indefinitely, but these 39 foods significantly decrease in quality if they reach subzero temperatures.
