The EDP have teamed up with Go Entertain to give away 20 DVD box sets of Bang Goes The Theory, the fun-packed BBC show that looks at how science shapes the world around us, tackling everything from astrophysics to zoology by way of lie detectors, water-powered jet packs and a toffee-powered rocket!

Available from amazon.co.uk from 12 September, Go Entertain's great new Bang Goes The Theory: The Compete Series 1 & 2 box set features all 18 episodes from the show's first two seasons and an hour-long special programme!
