Dick and Dom head underground to reveal the three tunnelling geniuses whose ideas revolutionised the way people dig below the earth. They put dynamite to the test, visit the world's largest boring drill, and build their own tunnelling robot.

Dick and Dom head to the home of the skyscraper: New York city. They become human guinea pigs at a lift-testing facility, get up close to a steelworks and attempt to build their own skyscraper.

Dick and Dom enter the world of engineering against floods, wind and earthquakes. In the Netherlands they see how coastal defences keeps the sea at bay, put earthquake proofing to the test and tackle gale-force winds.

Dick and Dom go super-sized in this massive movers spectacular in which they trace the origins of the genius ideas that have made shifting heavy weights a whole lot easier. In their element, the boys head to a scrapyard to find out how hydraulic grabbers work, get up close to one of the weirdest looking aircraft ever built and get to grips, literally, with the world's largest hydraulic hand.

Dick and Dom's quest takes them into the world of renewable energy. In the Nevada desert, they discover how the sun's energy could keep the world powered forever. At the Hoover Dam, they uncover the genius behind how a lake can generate power.

Dick and Dom are under attack in this tour through defensive engineering. The boys delve into the work of three geniuses whose ideas have given us impregnable castles, reinforced concrete bunkers and may protect Earth from asteroid attack.
