Why does Water Expand when it Freezes?

The Nobel prizes feature on the Naked Scientists this week alongside a bumper crop of your science questions! We find out why water expands when it freezes, whether animals have regional accents, and how many rockets you would need to crash into the moon to knock it off course. Plus, how the insects splattered on windscreens are helping scientists to study biodiversity, the virus linked to chronic fatigue syndrome and the prospect of a paper-thin digital camera. Also, We find out how India is coping with the IT boom, and show you how to make a spud gun from stationery! Like this podcast? Please help us by supporting the Naked Scientists
