S4 E3 • Battling Nature

Dick and Dom go head to head with the fiercest forces in nature as they enter the genius world of engineering against floods, wind and earthquakes. They head to the Netherlands to see how one of the world's great coastal defences keeps the sea at bay, find a suitably hair-raising method to put earthquake proofing to the test and tackle gale-force winds in their bid to storm-proof their most precious possessions.

S4 E4 • Massive Movers

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.

S4 E5 • Everlasting Energy

Dick and Dom's quest takes them into the frazzling, windy and fast-flowing world of renewable energy. Heading deep into the searing Nevada desert, the pair discover how the sun's energy could keep the world powered forever, at the iconic Hoover Dam, they uncover the genius behind how a vast lake can generate epic amounts of power, before they put all they've learnt to the test with their own suitably wacky take on a power station.

S4 E6 • Under Attack

Dick and Dom are under attack in this high-octane 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 one day protect planet Earth from asteroid attack! To top things off, they head to the seaside for a mega-sized game of smash the sandcastle.

S4 E7 • Epic Bridges

Dick and Dom turn their attention to the incredible world of monster bridges, tracing the genius ideas that have taken us from ancient Roman arches to elegant cable-stayed suspension spans, to a future where we may see bridges 3D-printed by robots. In their challenge, the boys join the Royal Engineers for an army bridge-build race... complete with a severe dressing-down for the loser.

S4 E8 • Ultimate Playground

Dick and Dom sample all the fun of the fair in this thrill-ride through the engineering genius of roller coasters and water slides. As well as learning how coasters somehow stay on the track when upside down, the boys don their swim shorts and bravely research the science behind the world's fastest waterslides. Then they put their theories to the test with an epic slide challenge which attempts to topple a record owned by a certain Usain Bolt.
