The elastic mouth piece is connected to the underneath of the cap, all as one piece, where it holds the straw in place (the left picture shows the tube connecting the mouth piece and the straw holder). As you bend the mouth piece into a "closed" position (right picture), potential energy is stored in the elastic, as the tube is bent. When you push the button underneath the mouth piece, it pushes the white component (as seen in picture on left), releasing it from the gray catch connected to the mouth piece, and releasing kinetic energy as the mouth piece pops out into "ready-to-drink" position.
Taken on 4th floor San Jacinto Residence Hall.
