Just tell me why it aint possible.  I mean come on, just look around you, look at the things you do each day. Even now do you think its not possible? Then you are wrong.
Just think about it. When you feel hot, dont you take a card or paper and swipe it. Dont you get fresh air now. How? There was air before also. But its strenght wasnt enough to suffice your thirst. But now when you used that card and moved it left and right, more air came rushing. But from where? The air was already there but this time you put your effort and strenght, so air quenched your thirst.
Hmmm... Right!
Think about it. And tell me.
