Capillary forces are attractive forces created by the surface tension of a molecular layer of absorbed water that forms between two surfaces. Gecko toes are well-studied and their sticky properties have inspired some incredible technology, such as stitch-free ways to seal wounds and sticky handheld paddles that may help soldiers scale walls someday. As a result, the tiny hairs touch so much surface area so closely that weak forces of attraction between molecules in the hairs and in whatever surface the animal is walking on add up and become sufficient to let the gecko hang on.
