Hazzy Wrote:Gravity would pull you out. The water stays there because sealing off the top and sucking the air out creates a pressure imbalance. 14 lbs/in^2 of force push the water up, and 9.8*waterMass push the water down, approximately.

Does someone know how to do that math? I sucked at fluid dynamics in Physics.

More importantly, the surface tension is what holds the liquid in the straw. It's narrow enough to allow that.
