BOOK Why Don't Penguins Feet Freeze? (NewScientist) - 3.5/5
My grandmother gave this to me, it was my late grandfathers and it's pretty interesting, it's just interesting questions being answered by NewScientist readers. As for why penguins (Tux reference?) feet don't freeze, it seems that the arteries that go to their feet are in pairs one hot, and one cold, so the heat is transfered to the cooler artery rather than the floor! Yeah, just an interesting book
