The zip is an invention which we all use in our daily life.It is an easy and interesting process.First you must connect the two teeth strips with the latching mechanism. Then the user will pull the latching mechanism(slide) upwords so the teeth are push towards the hollows of each track. To open the zip the user should simply pull the slide downwords so the two sides of the track are separated. Zips keep most of our bags and jackets shut and this would be all but impossible without modern manufacturing technology.
