Episode 3

BBC Three's first science series marches on with self-confessed science geek Greg Foot leading the way.

Greg squares up to champion cage fighter Rosie Sexton and friends to discover if winning unfair fights only happens in the movies. He asks perhaps the ultimate science question - why is the sky blue? - before probing the urban legend that your eyeballs fall out if you sneeze with your eyes open.

And, as if that was not enough, Greg experiences the highs and lows of surviving on your own bodily fluids. Not your average half hour in front of the telly!
