Hiccups and Helium
Why does helium make our voices higher? What are hiccups and how can we get rid of them? How contagious is swine flu? We take on these questions on this weeks podcast as well as find out how beta blockers slow our heart rate down, why food sticks to the bottom of a pan when it burns and how sewage waste is moved round an aeroplane. Plus, we look into the role of the prostate in men and the conditions associated with this organ.
