Neon is a gas that glows when you run electricity through it. So many people make Neon lights and bend the glass tubes of neon into shapes and letters and stuff for fun.

Neon would only be used in a refrigerator for lighting but when you put your food and drinks inthere you might bump the glass and break the lights, so no one put the lights in there.

Freon is a name for a chemical made by DuPont corporation that is really a long name Trichlorofluoromethane, a product that is sort of harmful to the Earth. It is neat because when you compress it to a liquid and then expand it as a gas it is really cold.

So people thought that this would work great in keeping food cold and also to put in fire extinguishers.
