How do Dolphins Drink?

24 September 2010
Presented by Chris Smith, Sue Marchant.

How do dolphins and other marine animals hydrate themselves? Can we use nanotechnology to fight disease? How does a radio-controlled clock work? We take on this variety of questions as well as find out why tea stains our cups, whether volcanic activity hollows out the earths core and why ice sticks to your tongue. Plus, we investigate if any large land animals can survive without oxygen!
