How Do They Do It?

The programme examines how cheddar cheese, often described as the world’s favourite cheese, is produced from milk to the finished block. It also explores the internal mechanisms of Resusci Anne, the mannequin that serves as a training tool for CPR techniques.

The programme titled Cheddar Cheese/CPR Mannequins is a single episode that forms part of a larger series. It is presented as a factual look‑in, aiming to give viewers insight into two seemingly unrelated subjects. The episode is structured in a straightforward, documentary‑style format, keeping the focus firmly on the topics it covers without any fictional embellishment. In the first part of the show, the production chain behind cheddar cheese is examined. The segment explains how this particular variety, often described as the world’s most popular cheese, is created from start to finish, detailing the steps that turn milk into the familiar block of cheddar. The second half shifts to the inner workings of Resusci Anne, the mannequin widely used as a teaching aid for cardiopulmonary resuscitation, and outlines the mechanisms that allow it to simulate human breathing and pulse for training purposes. The episode therefore offers a dual‑focus narrative: one that demystifies the traditional craft of cheddar making, and another that pulls back the curtain on the technology embedded within a CPR training dummy. By juxtaposing a centuries‑old food‑production process with modern medical‑training equipment, the programme provides a concise yet informative snapshot of both culinary heritage and lifesaving education.
