(Van der Waals forces explain why geckos can stick themselves to ceilings using zillions of tiny hairs on their toes.) Although there is only a microscopic amount of van der Waals force between one microfiber and any given dirt particle, remember that there are millions of microfibers in a...
This invention came from observing the gravity-defying way that geckos walk on walls. Geckos tend to stick to the surfaces they walk on with the help of similar sticky toe pads. The adhesive limbs of a gecko allow it to smoothly walk up walls. (Photo Credit : Papa Bravo/Shutterstock) ...
