Dry ice seems so magical, and it is! Follow these rules when handling it to stay safe on Halloween however you use it: in drinks, punch bowls, and more.
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]
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.
Dry ice bombs are commonly made from a container such as a plastic bottle, water and dry ice. The bottle is partly filled with water. Chunks of dry ice are added and the container is closed tightly. As the solid carbon dioxide warms, it sublimates to gas and the pressure in the bottle increases.
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
The dry ice color show is usually performed in classrooms to demonstrate the properties of acids and bases, their effect on pH indicators, and the sublimation of dry ice. Setup is simple and generally involves only minor hazards, the main one being the low temperature of dry ice, which can cause frostbite upon skin contact.
