More info:

Almost everybody uses a zip from day to day. But how many people actually knows how it works?

It is made from two sets of locking teeth. It’s a similar idea to weaving the fingers on each hand together.

It’s slightly more complex than that though and it took Gideon Sundback around 7 years to perfect it.
