A company in Ann Arbor has found a way to genetically alter silkworms with spider DNA so they now spin spider silk, one of the toughest materials in nature.


According to Defense One, the new material designed by a company called Kraig Biocraft, is almost as tough as Kevlar plastic, but, (if it works) "Dragon Silk", as they call it, will be much more elastic than Kevlar.

Spider silk is five times stronger as the same weight of steel. And can be stretched five times it's length without breaking.
