Ask The Naked Scientists Podcast

This week we're exploring why swimming on a full stomach might cause a cramp, whether it's really true that joints ache more when the weather's cold, and why does tapping the top of a beer bottle make the drink explode?

Join Dr Chris and Kieno Kammies for this week's Ask the Naked Scientist, to find out! Like this podcast? Please help us by supporting the Naked Scientists
