Wrexham Science Festival

The Wrexham Science Festival is now in its tenth year. It runs from 6th - 15th March and it's a cornucopia of talks, films, demonstrations and exhibitions on a huge variety of scientific and technological topics. In this week's programme Adam Walton reports from the Festival and meets some of the scientists who'll be there.

He takes a deep breath and tries out a piece of kit called a rebreather which keeps both deep sea divers and astronauts alive. We hear about the properties and the scientific history of oxygen and look into the mystery of the expanding marshmallow. Adam also discovers why computers can't translate for toffee and why snakes have forked tongues. And finally - and we've chosen that word carefully - he considers how science has informed film-maker's visions of the end of the world.
