Plus, serial inventor Chris Elsworthy has engineered an innovative power tool that combines all your drilling and sawing needs into one handy box. Diane White and Tim Bhullar have something for the kids, and get a helping hand in the Den from a giant tomato and a giant banana. Their range of books aims to encourage kids to eat their five-a-day... Afterwards, at 10.00pm, Simon Amstell finds himself depressed and in the midst of a life crisis. I don't blame him.
