Did you know?

Stronger than bone and twice as elastic as nylon, spider silk has already proven its usefulness to spiders, but now scientists are looking into its potential importance to humans as well. Research is underway around the world to fabricate the tenacious fibers in the lab, and scientists hope to someday outfit soldiers and police in bullet-proof vests made of mass-produced spider silk. Some say spider silk can stop more than just a speeding bullet: Many experts claim that the silk of an orb weaver spider is so strong that a strand as thick as a pencil could stop a jumbo jet in flight.
