Where do you find fluorine?

You can find fluorine in toothpaste and in some city water supplies, because fluorine strengthens teeth and helps prevent tooth decay. It does not affect the taste, scent, or appearance of water, however.

You can't find pure fluorine anywhere (well, other than from a specialty gas supplier), because it's too reactive to exist in nature. It reacts explosively with carbon and hydrocarbons, as the first person to try to make flurocarbons found out (he lost two labs that way).
