Most of us shriek when we see or walk into spider web. Before you destroy a web think about engineering and silk of which it is made.

Spiders can make up to seven different kinds of silk.

Silk turns from liquid to solid when it hits the air.

Silk has a tensile strength stronger than steel at the same density.

Silk has inspired fibers like Kevlar used in bullet proof vests.

Silk has biomedical applications like silk scaffolding for nerve regeneration and super fine medical sutures.
