Best Answer - Chosen by Asker:

Well, the teeth of the zipper are designed so they interlock. The zipper slide is designed so that it forces the teeth together as they are squeezed out the bottom of the slide, thus causing them to "snap" together. The top of the slide separates the two halves causing them to separate and open.
