The straw is not empty; there is air inside the straw.When we dip the straw in any liquid and suck on one end of the straw, we are sucking the air out of the straw (it goes into our mouth). Now the atmosphere is pushing down on the liquid in the glass, so the liquid rises into the straw from the other end, and goes into our mouth.If we do not suck on the straw, the liquid will not rise in the straw.
