van der Walls Gecko

Just finished this one - the toes of Geckos have millions of these tiny spatula-tipped hairs called setae which is what allows them to stick to and climb almost any surface with ease. It's all due to what scientists call "van der Walls" forces which create a kind of electromagnetic pull on an object... it's all to do with how densely packed and teeney tiny the little hair things (setae) on thier feet are.
