Can you electrocute weeds? Why do teeth go wobbly? And which cells last a lifetime? In this bumper edition of the Naked Scientists, we tackle your pressing science questions and find out how the shuttle manoeuvres in space, what makes wounds itch, whether reverse osmosis can make moonshine and if static can stick a cat to a wall. Plus, how diamonds deal death to tumours, cooperation in the elephant world and an update on the Japanese earthquake situation. We also hear how a hairy leg can help you bend water to your will, and Diana discovers why potato peelers never need sharpening! Like this podcast? Please help us by supporting the Naked Scientists
