Engineer Marshall Brain, author of How Stuff Works, translates his passion for "stuff" into an upbeat new TV series. As tour guide, Brain focuses on things made in America, showing how workers and state-of-the-art machines create objects of desire and fascination.

This three-part series begins with a visit to Trek Bikes in Wisconsin to explore how their road bike is made from the same lightweight, super strong material used to make stealth bombers. The second episode features factories making speedboats and golf balls, and finishes at the famous Zambelli fireworks company. In episode three, he examines how cars, airbags, and money are made.
