In the scene when we first see Jack in Davy Jones' locker (after the scenes with all the Jacks doing different things on the ship) after he says 'Gentlemen, I wash my hands of this weirdness" and slides down the roap, he licks his finger, holds it up, and says "no wind." Then he walks a little ways. He stops and says he wants "..a gust, a whisper, a tiny lick..." While he is saying this (and after he stops speaking), his hair is blowing slightly.
