When you reduce the air pressure inside the straw it causes a suction. The pressure of the air outside the strawis then greater than the air pressure inside the straw, then the liquid goes up the straw. When we drink a fluid we create a vaccum by sucking the air out of the straw.

Explanation:
A drinking straw is used by creating suction with the mouth. This causes a decrease in air pressure inside the straw. Since pressure acting on the surface of the drink is equal to atmospheric pressure, so this greater pressure pushes the soft drink up the straw into the mouth.
