In 1939, Practical Mechanics responded to the start of the Second World War by showing its readers how to build their own air raid shelter.The design had similarities with the Anderson Shelter, a build-at-home structure made from corrugated steel, to protect from flying bomb debris; that saved many lives during the Blitz. To get some inspiration, Ivan and Jenny make a poignant trip to see a real life Anderson Shelter at a nearby War Museum.The team decide to reinvent the Anderson Shelter as a hi-tech garden shed, with solar panels and grow lights.Engineers Jenny and Ellis are paired together to work on the second reinvention project – a pedal-powered washing machine.It's a design that could have a real purpose in the modern world, as more than 60% of the world's population don't have access to an electric washing machine; could pedal-power offer a solution?The pair decide to make a washing and drying machine, made from scrap parts sourced from a local reclamation yard.
