He uses a marshmallow to model the boy’s head, a glass of water to model his stomach contents and a balloon to model his lungs. These items are placed inside a bell jar, which is then evacuated using a pump. The marshmallow expands, the balloon bursts and the water boils at its existing temperature of 37 degrees Celsius. Kevin explains that boiling is not solely caused by increasing temperature. This clip is from the BBC series How to Survive in Space. Dr Kevin Fong opens a window onto today’s most exciting space missions, explores the future of space travel, and offers a unique insight into the challenges of protecting human life in the hostile environment of space, as part of the 2015 Royal Institution Christmas Lectures.
