Geckos' feet are right up there with adhesive tape, when it comes to being able to stick to things. Unlike tape, however, those feet retain their adhesive qualities even after many, many uses. Now, thanks to research being conducted at Carnegie Mellon University and Germany's Karlsruhe Institute of Technology, we may one day be using self-cleaning reusable gecko-inspired tape.
