Why Don't Penguins' Feet Freeze?: And 114 Other Questions NewScientist

Why don’t penguins feet freeze? Well it turns out they can control the blood flow to their feet and they also have a system of blood vessels that reduces heat loss from their bodies. These both help them to keep their feet a few degrees above freezing. This also stops them sticking to the ice.
All the questions are from a write-in column in the New Scientist magazine. They all have multiple answers, are often fairly simplified, and all take the question from a different and new perspective. There’s also a few joke answers scattered about help to break up some of the necessarily longer answers from complex questions. The book is perfect to pick up and put down whenever you’ve got a minute or if you just want to learn something new.
So, if you fancy being able to crack out some interesting, but probably useless, facts to your friends and family, this is the book for you.
