What makes up a comet? It’s like a dirty snowball, but not. To simulate the ingredients of a comet, start with some water, carbon, sand, alcohol, and dry ice. Squeeze it together and see the incredible result.
The solid nucleus or core of a comet consists mostly of ice and dust coated with dark organic material, according to NASA, with the ice composed mainly of frozen water but perhaps other frozen substances as well, such as ammonia, carbon dioxide, carbon monoxide and methane. The nucleus may have a small rocky core.
