Clothed Questions - Naked Answers
|
Black holes, bright birds and ice evaporating in the freezer all come under scrutiny in this week's Naked Science Question and Answer Show. We also find out why space is so cold, what happens when a neutron star collapses and where houseflies buzz off to in winter. Plus, we discover a robot who keeps kids company in hospital, and catch up with the the latest tech news about Twitter. Also, we hear How bats are louder than a rock concert, how a quantum trick could let birds see magnetism and we peer into the biggest eye in the animal kingdom - belonging to the Colossal Squid. Plus, in Kitchen Science, we get close to some hot rubber!
