Naked Science Question and Answer

The Naked Scientists are back to answer all your burning science questions. Dr Chris, Dave and Helen tackle hot flushes, why spiders love living in our houses, how many stars are in the Milky Way, and why cows in a field always face in the same direction... We will also be connecting direct to Norwich, the host of this year's British Association Science Festival, to hear about a world record attempt at the most people in a bubble, and sticking with bubbles, Dave and Derek make lava lamps in Kitchen Science.
