A team of researchers at the University of Zurich led by Stefan Seeger has come up with a super water repellant fabric.
The new fabric is apparently made from folyester fibres, which are coated with millions of silicone filaments. Apparently jets of water just bounce off the special fabric, and drops of water will roll off of its surface if it is tilted just two degrees. The "hydrophobic" solicone nanofilaments are what make the fabric so water repellent that the water never even touches the polyester fabric.
I wonder if they can make a coating for car windshields?
This could spell the end of wet umbrella's too...
