Why don't penguins' feet freeze?

Today I finished this excellent book published by the people at NewScientist. It's a follow-up to their highly successful "Does anything eat wasps?" and contains all sorts of interesting (and some uninteresting) facts that people often ponder - such as:
What time is it at the North Pole?
Should you pickle your conkers?
Why do boomerangs come back?
Why does hair turn grey? (fortunately not something I've had to worry about yet!)
Anyhow, if you have a spare £7.99 available (and especially if you're one of my friends that has a 'grey' issue!) this is worth a buy.
