How does a zipper work?
TechnologyEveryday Objects
Quick Answer
A zipper joins two rows of teeth by forcing them together with a sliding piece called the slider. The slider interlocks and separates the teeth as it moves.
The Full Story
A zipper has two rows of teeth or coils attached to fabric and a slider that guides them into a single connected line. As the slider moves upward or downward, it presses the teeth together on one side and pulls them apart on the other. The design was perfected in the early 20th century and became widely used in clothing, luggage, and gear. Modern zippers can be made from metal, plastic, or nylon coil. Though simple, the mechanism is an elegant example of mechanical interlocking.
