All of you who believe it's suction probably believe that with a strong enough pump a fire truck can suck water up to a bridge 50 feet above the water. Of course the real firemen in the group as well as every physicist on earth know that we can only pull the water up a maximum of 34 feet (after that it boils in the pipe, which is why well water is pushed out of the well by a pump at the bottom). At that point the weight of the atmosphere is equal to the weight of the water.

If I open the door to the dark room will all of the dark get out?
