Question and Answer Catch up!

This week, Chris and Co are back from their holidays!  So they're tackling their bulging mailbag of your questions.  We discuss how scientists have been given the green light to cross human DNA with animal cells all in the name of medicine, eavesdroppers in your garden - the plants that respond to sound, and the world's smallest thermometer - only one molecule!  We also tackle questions on keeping your beer cool on the beach, massive melons and the horticultural properties of wee.  We find out about how radio shows can give Pygmies a voice and how anyone can have an out of body experience now that scientists have discovered how to trick your senses into making them happen.  Plus, in Kitchen Science, Dave shows us how to make eerie music with a wine glass!

  • Why does a wet towel cool beer?

    If you wrap a beer on the beach, on a hot day, in a wet towel and leave it in the sun it will cool down which seems unlikely but not impossible and I think the key to this is latent heat of vaporisation. What do you think?

How about her doing a voiceover for an advert for that washing-up liquid that leaves crockery "Squeaky Spleen"! DoctorBeaver, Mon, 10th Sep 2007

I think a whole new section on the show, could be where "we" ask Kat to make noises of different cells and body parts. I would tune in just to hear them every week. Amazingly funny., Thu, 5th Nov 2009
