The vortex, a natural phenomenon, underlies the design of the drinking straw. Because of a fi ne spiral cut into the
narrow glass tube, any liquid that passes though it acquires a powerful vortex motion. As seen in nature – tornadoes, for example, or wildly-fl owing rivers or ocean waves – the vortex action increases the intensity of the energy.
The delicate structure of the hand-blown drinking straw takes its shape from the golden ratio.
For ease of cleaning, the straw comes with a bottle brush of the appropriate size.
