I remember reading several different times that scientists are studying spider's silk because, relative to its size or something (this is all off the top of my head), it is the strongest and most elastic substance on earth.  It could be revolutionary in several fields, including sportswear and accessories.  Also, spiders are my favorite animal. I miss my Georgie, she was of the "eight-legged human" variety and as big as my hand; she had them long model legs :(
