Bursting Bubbles, Counting Calories and Falling to Earth!

On this weeks Ask the Naked Scientists we find out how to live a healthy lifestyle. We count calories to see just how many we burn during exercise, we work out how to lose weight the healthy way and we discuss the difference between calories and fat. We also discover why coloured bubble bath produces white bubbles, whether removing salt from the ocean could reduce our chances of flooding and whether animals know about natural disasters before we do! All that and many more of your questions answered on this weeks Naked Scientists.
