A piston is movably disposed within the internal cylinder and includes a hollow portion in communication with a device for drawing air. The piston is movable within the internal cylinder to align the hollow portion with a predetermined number of the plurality of holes for selectively drawing air from the predetermined number of the plurality of holes.
