Abstract
Drinking straws for aerating fluids are described. A straw includes a body and a cover. The body defines a flow space and an aeration area. The cover includes an aeration opening and a movable barrier. The cover encloses the body and the movable barrier can move between a first position occluding the aeration area and a second position exposing a portion of the aeration area. The straw body and the straw cover, when in the second position, enable air flow through the exposed portion of the aeration area so as to aerate fluid flowing through the flow space. The straw body and the straw cover dampen sound created by the aeration of the fluid when in the second position. The movable barrier may be a plug or a slider.
