If you've ever dropped your phone in the toilet or bath you might want to 'nanocoat' your phone.

Phones could be made water resistant by a special machine that coats gadgets in a layer of waterproof particles thinner than a single strand of hair.

The technology is so effective even tissue paper can be made waterproof.
