Why do spiders face down in their webs?

Jeffrey Schuh  asked the Naked Scientists:
   
Hi,
I discovered your show a couple months ago, and am trying to catch up with your archived shows.  Are you folks really naked?  It's hard to tell on the radio.

Anyway, I have a question about spiders.  As far as I have noticed, most, if not all orb spiders that I've seen face downwards when in their web waiting for prey.  Is there a known reason for this?

And, have you ever hummed at a spider?

What do you think?

If brains were made of dynamite, I wouldn't have enough to blow my nose.

No, I can't say as I have ever hummed or serenaded any insect, arachnid, mollusc's etc. Can I ask why you make this strange enquiry? Have you?
