Abstract: An expandable drinking and mixing straw apparatus that can be compactly stored and expanded when necessary to provide a deployed dual-functionality mixing and drinking apparatus. The several embodiments of the straw apparatus provide a unified apparatus as well as functionally equivalent embodiments with two straw sub-component members defined by an outer straw and an inner straw which sub-component members are bonded together at specified locations. When force is applied to the undeployed straw apparatus, a plurality of veins expands from the apparatus to provide mixing functionality without compromising suction functionality. Straw sub component bonding, vein bending and stopping, and method of deployment of the drinking and mixing straw apparatus are disclosed.
