the passage :
It sounds like a sequel to "Spiderman: The Movie"—Spidergoat! OK, maybe not, but it is a very interesting application of transgenics. Spider silk is the strongest material known; it's 5 times stronger than steel and twice as strong as Kevlar. People have actually tried starting "spider farms" to harvest silk, but the spiders are too aggressive and territorial to live close together. They also like to eat each other.
When the genes for spider silk were put into a goat and produced in the goat’s milk, however, the transgenic animal produced silk proteins in its milk that could be spun into a fine thread with all the properties of spider-made silk. This material can be used to make lighter, stronger bulletproof vests, thinner thread for surgery, and stitches or indestructible clothes.
