When you breathe on a window, your breath condenses, and fogs the window up.
But, if you have had a sticker on the window, say a parking permit for instance, and you remove it. When you breathe on the window, the area around where the sticker was steams up, but the area where the sticker was doesn't.
Can anyone explain this to me?
