First up this week is Isabel O'Donovan with her tasty handmade chocolates, tempting the dragons with chocolate is certainly one way to their heart, but will it be enough for Issy? Gavin's 'ideal' voice may not be suitable for Dave Carthy's Voice Control system, but can he switch on the other dragons? And with a cold winter and short supplies of water, Tony O'Briens Stopcock Cosy is certainly in season. Bobby goes for a ride with Robert Rae's suspension bike while Daudi's hoping an investment of 50,000 will help launch his sports utility bag.
