	That's a push, not a pull.

	If you dip a straw into a glass of water, and "suck", all you're doing 
is forcing your diaphragm to go down a bit, causing your lungs to 
expand. This creates a region of low pressure in your lungs, and the 
atmospheric pressure *outside* is what will actually push the water into 
your mouth - it's a push by the atmosphere, not a pull by you.
