It’s the perfect Christmas present for the person who has everything…except, perhaps, self-respect.
Scientists have invented a pair of high-tech socks which, when filled with urine, and activated by the wearer’s footsteps, produce enough power to send a message. So when nature calls, so will the socks.
Inventors at the University of the West of England in Bristol claim they could be used in an emergency to transmit a person’s coordinates, showing rescue teams that a person is alive and needing assistance (and, presumably, fresh socks.)
