The liquid silk is made

                    by silk glands inside

                    a spider’s body. The

                    glands are linked to
                    spinnerets at its tail

                    end. As the silk comes

                    out of the spinnerets
                    it instantly hardens

                    into fibers. The spider

                    pulls on these to draw

                    them out, and the harder

                    it pulls, the stronger the
                    silk becomes.                                           Soft, strong silk is ideal
                                                                              for protecting this
                                                                                 spider’s eggs.
