Why don't Penguins Feet Freeze

I've just read your excellent book and have enjoyed it thoroughly

However the answer to the title question left me wondering a little as to be honest the answers given were more of a "why doesn't a Penguin lose too much heat through it's feet."

I've worked in a frozen food vendor and I know that on Mondays when the freezers were right down to temperature of near -30 I would stick to surfaces if I was daft enough to touch them (it had to be tried - not that I'm recommending it!).

I know really cold snow is powdery, but still that layer of cells in contact must be -30 or so on one side and above freezing on the other. Why are they not killed ?

Many animals have dead cells "fur etc." in contact, but not Penguins as far as I know

So if it's OK can I ask it again please

Regards

Andy

I have heard that submarines travel faster in colder water. Why?

A chest cold made my voice deeper (and sexier apparently). What caused this? Can I get the deep voice without the cold?

Why does cold weather dry my skin out?

Generally things dry out more slowly the colder it is, yet as soon as winter arrives my hands become so dry the skin splits.

No Ice Under Bridges

I was walking along a canal several days ago, and, the UK weather being what it is at the moment, the canal was frozen. However under all the bridges that crossed the canal, whether footbridge or road bridge, the water was unfrozen. What is it about the bridges that stops the water under them from freezing?

Does a room get hotter when you boil a pot of water?

My girlfriend and I were having an argument the other day. Sometimes when it is cold in the kitchen, I turn in the gas hob to warm the place up. The argument is that she claims that the room gets hotter if you put a pot of water on the hob to boil and let the room get steamy. I disagree and think that the room gets just as hot without boiling a pot of water.

Who is right? Does the room get hotter with the pot of water or does the room get just as hot without it?

How do waterfalls freeze?

After visiting Iceland last year you could see frozen waterfalls coming down from the cliffs? How do these freeze since surely they have too much kinetic energy?
