Is it possible to catch a fish, caught in an extreme situation and not having anything on hand for this? But the button that you have? And to dissolve any knitted thing, to get thread for fishing line? Then you are saved. At the end of the thread tie the head, and slightly above — button. Fish eat it together with the nozzle and then wanting to get rid of inedible, habitually sends it outward through the gills. When fitting the thread button jam the Gill slits of fish caught! No, not fishing stories and famous cases.
