It is more practical than ordinary ice because it takes up less space and it’s 142c colder. Since it turns into steam instead of melting into water, it is cleaner to use. For these masons, it is extremely popular, and many people prefer it to ordinary ice. Dry ice is so cold that ff you touch it with you bare fingers, it will burn you.
