Freon is a trade name for a chemical envented by Dupont 70+ years ago to replace dangerous, poisonous or explosive gasses used for refrigeration. The chemical is the famous CFC. Comonly called R-12, however, there are many other refrigerants (like R-11, R-502). These chemicals were pulled out of production in 1995 due to environmental concerns. The actual environmental impact of CFCs has yet to be determined.

Get the freonmug. The Japanese art of paper-folding. To make more complex origami you will need to learn terms such as swivel fold, petal fold, prelinary base, etc.
