I'm little confused about some questions related to van der waals forces.
How do van der waals forces hold molecules together? (also structurally) And how does it work in holding a gecko along the glass? What role does tiny hairs perform present on a gecko's foot? (I read somewhere that "The reason a gecko foot adheres--and yours doesn't--is that it is coated with millions of tiny hairs") Are those the reasons in holding it along the glass or van der waal forces?
