A light-hearted and humorous look at real-life inventors, contraptions and gadgets with the much-loved duo, beginning with inventions inspired by nature. Wallace and Gromit learn about flying penguins, German robots, and Dutch sculptor Theo Jansen. Plus, Jem Stansfield meets a man who has created gills that could allow humans to breathe under water. Narrated by Ashley Jensen.

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.

Wallace and Gromit experience the world through the five senses, exploring the fact and fiction behind invisibility cloaks, bomb-detecting bees and the top sensory inventions.
