Better spider silk | Does even more than a spider can | The Economist

I've always loved the stories of attempted spider-farming:

"Compared with silkworms, spiders are aggressive and will eat one another, making it inadvisable to keep many spiders together in the same space." (Wikipedia)

I'll have to track down the historical account I came across a few years ago, but the idea of frustrated scientists watching their spider herds consume each other is priceless.  It's like farming tigers.
