We've all worn jeans, or at the very least something with a zipper.

Zips are seemingly simple contraptions, like a little train on a flexible track - pull up to close, down to open.

Some zippers actually lock into place, and apparently it's controlled by the tab part of the zip and what way it's positioned.
