Travelers at Miami Airport got quite a scare recently when a can of hairspray exploded. Who knew hairspray could be so dangerous? We were both so free and careless with it in the 1980s when we sprayed a half-can of Aqua Net in our hair before we went out. I hate to think of how many people we could have harmed in smoke-filled, crowded nightclubs. Not to mention the fact that we’ve probably played a big role in causing global warming. Don’t worry; our reduced lung capacity is punishment enough.
