Stripping down science, the naked scientists. Hello it's Sunday October 3rd. Welcome to the Naked Scientists I'm Chris Smith and

this week we're taking on your science questions including finding out what is the hardest bone in the body to break

I suspect some people have had a go at breaking every single one of theirs maybe we'll find out

also where the magnets get their energy from and what causes the bright

patterns that you see when you rub your eyes? Also here on the show this week is the

I'm intrigued, thank you Dave.

world of science this week. Dave what have you got for us first?

Wright brothers first took to the air. Aircraft has been controlled by moving surfaces

which deflect the air and therefore the aircraft gets deflecting the other direction
