The key to geckos’ unrivalled climbing skills isn’t sticky feet. It’s subatomic

While some creatures can traverse vertical and overhanging surfaces with the aid of sticky substances or suction, you need to zoom down to a subatomic level to truly understand how geckos seem to defy gravity. This video from the science documentary series Deep Look takes a dive into the subatomic world to explain how geckos can stroll on almost any surface due to the millions of microscopic pads on their feet, which possess electrons that sync up with the surfaces they touch. The short also offers a brief look at a Stanford University project to develop nanomaterials inspired by the astounding adhesive power of gecko feet.
