Gecko Feet Are Coated in an Ultra-Thin Layer of Lipids That Help Them Stay Sticky. All of that is amazing, but perhaps even more amazing is that despite their hyper-sticky feet, geckos move fast, running at speeds of up to 20 body lengths per second. 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. Geckos run up walls and scurry across ceilings with the help of tiny rows of hairs on their feet. From sticky feet to a sticky situation: what humans can learn from geckos Define each term.

Gecko Feet Are Coated in an Ultra-Thin Layer of Lipids That Help Them Stay Sticky. All of that is amazing, but perhaps even more amazing is that despite their hyper-sticky feet, geckos move fast, running at speeds of up to 20 body lengths per second. 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. Geckos run up walls and scurry across ceilings with the help of tiny rows of hairs on their feet. From sticky feet to a sticky situation: what humans can learn from geckos Define each term.
