Description

We rarely consider many of the objects which make up our world. How do they turn salt & pepper into Tobasco? How do they turn beans into decaf coffee? And how do they operate an unmanned autonomous helicopter? Simple things are often the products of the most extraorinary engineering processes. Each episode reveals the hidden story behind another familiar part of our lives.
