Abstract: The present invention is directed to a method of manufacturing a flexible drinking straw. The straw allows a user to easily suction liquid while preventing foreign bodies in the liquid from entering the mouth of a user. The straw comprises a tube defining a substantially constant cross-sectional inner channel, The tube has a multitude of fins extending from an inner wall of the tube to a distance from the inner wall. The fins create either a single or multiple liquid-way(s) that allow the liquid to flow freely while blocking foreign bodies that may be in the liquid. The straw comprises a tube with a cut and crimped end creating either single or multiple liquid-way(s) that allow liquid to flow freely while blocking foreign bodies.
