Listerine is responsible for the “Mouth Germs Extinction Theory”. A theory that shows us how Listerine mouth wash wipes out all the germs from people’s mouth. For show and prove this theory, we created a museum showing the extinct germs in bigger size and explained all about their universe.

Each handcrafted germ had its own name and story. Over 28,000 visitors explored their microscopic universe and the evolution of the “weapons” we’ve used to fight them, from primitive toothbrushes to modern oral care.
