Ozone Layer Protection and Gas Innovations

Brian Cox and Robin Ince talk hot air as they explore the pivotal role of gasses in our lives. Joining them to add some CO2 to the mix is material scientist Mark Miodownik, chemist Lucy Carpenter and comedian Dave Gorman. They discuss how humans came to even understand it existed in the first place as well as how many of the innovations in modern society have been underpinned by this mostly invisible and odourless substance. We laud the humble (or is it noble?) gas and its key role in technological innovation - from using laughing gas in anaesthesia to the combustion engine and of course the most important of all, the power source behind squirty cream.
