Hard at work !!

The silk that spiders produce is five to six times stronger than high-grade steel by weight, and is stronger than any known natural or synthetic fiber on Earth.  Spider silk is more durable and elastic than the strongest man-made fiber, Kevlar, which is used to fill bulletproof vests. 
It's so amazing to watch these creatures at work.  My extra is an upside down view that the spider said I could have -- no charge!
