Wow, if you thought Pet Rocks were total marketing genius, then behold the next step in brilliant ideas... Canned Air. No, not compressed canned air for cleaning keyboards, but actual cans of air from various cities around the world. Want to breathe in and sample Paris, New York City, Barcelona, Venice, Sydney, Dubai, London, or Tokyo? Well, skip the expensive trip and simply pop open one of these ingenious tin cans and inhale. All they need now are cans of Los Angeles Smog, Shanghai Pollution, or naturally sparkling Perri-Air canned on Planet Druidia. It's the perfect funny gag gift for any nostalgic world traveler or a good way for preppers to stock up for a global air shortage.
