Keywords: dry ice
I haven’t had to use dry ice for anything but I do know that it is made of carbon dioxide. You might know that as a gas, but when it is made into dry ice the carbon dioxide is solid. It is useful as it can be made colder than water and oxygen and scientists use it to freeze things. I work in a building where other scientists use it for their experiments!
