Remember Blue Peter's competition to design sonic devices for Doctor Who's Paternoster Gang? In this special to celebrate the return of the Doctor next weekend, Lindsey goes behind the scenes with the winners to see their Sonic Gauntlet, Lorgnette and Hat Pin in action - and they only run into Peter Capaldi, the new Doctor.
