Wallace and Gromit have always taken their safety into their own hands, and in this episode of the science series they consider other inventors with the same philosophy. They tell the tale of 1940s Hollywood starlet Hedy Lamarr, who had a side-line in inventing, and who devised a radio-controlled 'secret-communication' system for steering torpedoes to help allied forces in the war, the technology of which is featured in all modern bluetooth systems.
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.
Wallace and Gromit explore the mysteries behind man's fascination with flight, from 'homemade' space rockets in Manchester to jetpacks in the UK. There is also a look at some planes that unfortunately don't fly in another Contraption Countdown.
