Odor track / product design

Now it’s much safer to go deep into suburb areas such as mountains or woods for adventure or fun, because we have got Odor Track! Odor Track is a new thing that can tell what position you are when you are trapped in some desolate regions. With it fixed on your shoe, you’ll leave an invisible track on the path you have walked. A police dog can smell your odor track, and find where you are if any accident happens to you. What you should do is just to put a tablet-like volatile solid in the Odor Track, then fix it on your shoe, then it may give off odor molicule on the ground when walking.
