Today is National Zipper Day! 

Zippers are “a commonly used device for binding the edges of an opening of fabric or other flexible material, as on a garment or a bag.” They are used for “used in clothing, luggage and other bags, sporting goods, camping gear and other items.” It was in 1893 that Whitcomb Judson, a mechanical engineer from Chicago, invented the zipper.
