Funny, I liked geckoe, we call them talantara in Croatia. They can make milk poisoness if they end in the pot or glass of milk. Can you make explanation how do we stick to the earth surface. What is Gravity doing to a car that is roling on highway and not folling off the earth when passes from north hemisfere to south. ;)

But at the beginning they told that the feet of the gekos are charged and after a while they told that the vander wall forces are produced between two uncharged molecules?
Im a bit confused!

This went from Biology to Physics to Chemistry and back to Biology.
Also Evolution is super smart. It designed all that? Awesome!
