Home Sweet Home

The duo examine the world of domestic novelties, including a makeshift mill constructed by a young inventor from Malawi. There is a visit to inventor Trevor Baylis, a look at a collection of vintage tea-makers, former engineer and code breaker Tony Sale revives George the Robot, and science reporter Jem Stansfield meets an A-level student with a home-made fridge built out of scrap metal originally designed by Einstein.
