How Do They Do It?

The programme follows the building of the world’s most powerful locomotive, exploring the engineering challenges involved. It also shows how cow’s milk is transformed into clotted cream and demonstrates the process of shaping a boomerang from a single piece of wood.

Locomotive/Clotted Cream/Boomerang is a television episode that falls under the programme type and is presented as a single instalment within its series. The title itself hints at the three distinct subjects the episode tackles, and it adopts a straightforward, factual style throughout. The first segment follows the construction of what is billed as the world’s most powerful locomotive, tracing the steps taken to assemble this massive machine. The next part shifts focus to the dairy world, explaining how fresh cow’s milk is transformed into clotted cream through a simple yet precise process. Finally, the episode turns to woodworking, showing how a piece of timber can be shaped and finished into a functional boomerang. Beyond the core demonstrations, the programme highlights the expertise required in each field – from the engineering know‑how needed to build a record‑breaking locomotive, to the careful handling of milk that yields a traditional spread, and the craftsmanship involved in turning raw wood into a returning weapon. By juxtaposing these three activities, the episode offers a compact look at how different kinds of skill can turn ordinary materials into extraordinary results.
