How Machines Work 　　Produced by Cream Productions for Discovery Channel Canada, Discovery Science US, Discovery International. International Distribution: Cineflix International. 　　How Machines Work is a wicked trip inside, under, over and through the guts of ordinary - and extraordinary machines from our daily lives. Photo-real computer animation takes us where no camera crew can fit, or even survive. Entertaining commentary untangles complex design and engineering for all ages, while having fun along the way. Fly, flood, speed, spin, crush, cut, push, pull, tick, and tock. From a handheld tattoo machine to a coal-crushing power plant, an escalator, a machine gun, and a bomb robot. Fifty-two machines in 13 action-packed episodes make all of us experts on How Machines.
