    Spider silk is very strong. It can be stretched to 13% of its　　 normal length without breaking. It resists water and it is not affected　　 by extreme temperature changes. Spider silk also does not react to　　 chemicals. It is so thin that one piece of spider silk long enough to　　 reach around the world would weigh less then 1 half kilogram. The　　 publication "Discovery" reports it would take the life's work of 5000　　 spiders to produce enough silk for one woman's dress.

　　

    Military researchers, makers of medical supplies and clothing　　 designers are very interested in spider silk research. American army　　 and navy scientists believe spider silk could be used to make stronger　　 parachutes (降落伞) and bullet proof coats. Medical equipment companies　　 believe it could be placed inside the body and clothing makers think it　　 could make a strong, light weight material.

　　

    Researchers are trying to find a way to produce large amounts of　　 spider silk without using spiders.
