Cobweb is stronger than a steel wire !

                                              Cobweb is stronger than a steel wire !

We all have seen a cobweb. Spiders are spinning it. Though they are spinning it, they will not get trapped inside the web. Cobwebs are made of special proteins secreted by spiders. Cobwebs are beautiful to look. If we take one strand of cobweb and if we compare it with a strand of steel wire, surprisingly the strand of cobweb is more stronger than the steel wire !
Because of its chemical composition, it is more stronger than a mere steel wire. The main purpose of using the cobwebs by spiders are to catch its pray. If a pray comes inside a cobweb, it is very difficult to escape.
