Your Questions and Swallowing Swords

We get to the point of cutting edge Naked science this week, answering your science questions and exploring the science of sword swallowing.  We find out how the amazon could become a carbon criminal, learn how to predict the extent of an avalanche, and celebrate the passing of DD45 - an object that floated past the Earth inside the orbit of the Moon.  Plus, we find out if you can catch foot odour, if a bath full of vodka would get you drunk, and the delights of Liver a L'Orange!  Meera Senthilingam takes a 'thinking Walk' with Sir David Attenborough to learn about Charles Darwin, and Dave seems to defy physics by making bubbles that sink!

WoW, I didn't know about DD45!

And it was only 72000 km away!
A near brush with death you could say. Chemistry4me, Tue, 17th Mar 2009

I actaully heard a bit about it and was surprised how close. I did not pay enough attention at the time about the details, so that will be interesting to hear! Karen W., Tue, 17th Mar 2009
