How do geckos stick to walls without glue?
Quick Answer
Geckos cling using millions of tiny hair-like structures on their toes called setae, which create very weak electrical attractions with surfaces. This lets them run across walls and even ceilings.
The Full Story
Gecko adhesion is a classic example of a biological super-adaptation. The toe pads contain rows of microscopic setae that branch into even smaller spatula-shaped tips. These tips create van der Waals forces, tiny attractions that add up across millions of contacts. The grip is strong enough for climbing, but geckos can release it quickly by changing the angle of their feet.
