How It's Made

The series investigates how cut diamonds, wooden doors, paintballs and newspapers are produced, detailing the specific manufacturing steps involved. It also examines how these production processes have developed and been refined over the years, highlighting technological and methodological advances throughout the decades.

The episode is a programme that looks at the making of four very different products – cut diamonds, wooden doors, paintballs and newspapers – and it tracks how the techniques used to create them have changed over time. It’s presented as a single instalment that brings these varied industries together under one investigative lens. In the core of the show, viewers are taken through the step‑by‑step processes that turn raw material into the finished goods. The segment explains how a rough stone becomes a polished diamond, how timber is shaped into a door, how a paintball is assembled, and how paper is turned into a newspaper. Each of these manufacturing stages is shown alongside commentary on the ways the methods have been refined and updated through the years. The programme breaks down each product’s workflow, highlighting the key stages that define their production. It points out the specific actions involved in cutting a diamond, the carpentry work behind a wooden door, the filling and sealing of a paintball, and the printing presses that bring a newspaper to life. By focusing on these distinct steps, the episode illustrates the practical side of making everyday items. Finally, the episode draws attention to the evolution of these processes, noting how technological advances and new practices have reshaped each industry. It demonstrates that, while the end results may look familiar, the ways they’re achieved have continually adapted, reflecting broader changes in manufacturing over the years.
