Abstract: A light and edible straw includes a tube made of an edible material, microcapsules made of another edible material, and a protective film made of another edible material. The tube includes an internal face, an external face, an upper end face and a lower end face. The microcapsules are inserted in a wall of the tube. The protective film includes an internal portion covering the internal face of the tube, an external portion covering the external face of the tube, an upper annular portion covering the upper end face of the tube, and a lower annular portion covering the lower end face of the tube. Thus, the protective film keeps the tube from liquid.
