Spider Silks
2         In this lab we use spiders and their webs to conduct our research on the strengths and elastic characteristics of spider silks. Understanding the composition of spider silks will help us in the future to develop a strong stretchy material. According to Ball's article in Nature - spiders spring a trap, "The finding might help materials scientists to improve the synthetic fibres used in strong, lightweight, stretchy fabrics or protective coatings."
