How to make your phone waterproof, with new nano coating tech
Mobile phones could be made completely waterproof thanks to a new kind of nano technology.
It works by covering your phone with a special nano layer that is thinner than a single strand of hair.

It was revealed at the Consumer Electronics Show (CES) in Las Vegas, in America.
