Geckos stick to smooth glass using intermolecular forces
Millions of microscopic setae on gecko toes create van der Waals adhesion.
Gecko toe pads feature flexible ridges packed with microscopic hair-like structures called setae, which branch into billions of split tips called spatulae. Electrostatic van der Waals forces between these spatulae and surface molecules let geckos walk upside down on polished ceilings.

- Is this really a animals fact?
- Yes. It sits on the Animals shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
