It's true that "Bang Goes the Theory" has elements of Mythbusters, but it's focused on the science as opposed to the action movie stuff. The programme is basically "popular science -- you know, for teens!". Their magazine style format typically has one segment where they put a scientific hypothesis, law or principle in practice by building various gadgets. Other segments are news-related stuff, such as (just after the Japanese earthquake) a long segment on the science of tsunamis. I'm not in the target demographic at all, so I don't really follow it, but I appreciate their focus on educating kids and encouraging scientific thinking about young people.
