From jumbo jet engines to toilet paper, How Do They Do It? is a documentary series that goes behind the scenes and shows viewers how modern world items work and how they are made. Similar to the Canadian-produced documentary program "How It's Made," the show features two to three different products per episode and simultaneously breaks down the method in which these products work and shows the step-by-step process required to build it. Items and products featured on the show include hydroelectric dams, fish hooks, roller coasters and chewing gum. A British version of the show under the same name debuted in 2008.
