Laughter, Smell and Sounds
from Ask the Naked Scientists Hosted by Dr Chris Smith
How has laughter evolved? Why can'we tickle ourselves? Why do hot and cold water sound different? What is smell and why do things have a smell? We tackle these chalenges on this weeks show, as well as investigate if blood pressure varies in different sized people, why mouthwash makes water taste colder, investigate why we shouldn't breed with relatives and discuss the causes of vertigo.
