A straw that creates a vortex, water’s favorite motion.

The vortex, a natural phenomenon, underlies the design of the Calamus Straw. Unlike the other glassware that we carry, the Drinking Straw Calamus restructures beverages via a vortex motion as well as the Fibonacci sequence in the sections of the straw. Because of the fine striations cut into the narrow glass tube, liquids acquire a vortex motion, as they are drawn from one end of the straw to the other.

The vortex, one of the most powerful motions in Nature, for example tornadoes and turbulent ocean waves, is one of the ways that water keeps itself structured.


The delicate structure of this hand-blown drinking straw takes its shape from the Golden Ratio. It is a great gift and simple way to restructure all beverages on the go. It comes in a sturdy cardboard tube for safe transport and easy storage.


A straw brush, fitting this straw, is also available for purchase.


The straw is not recommended for children under 7 years old.
