Katherine Marie LeBeau received Patent #3,517,423 on June 30, 1970 for a “Fluid-Operated Zipper.” These are for the moments when the need to go is so great that you can’t spare the time or energy to manually operate your zipper. This amazing device makes use of “available fluids” and automatically releases the zipper, bringing relief to an otherwise-disastrous situation.

The instructions are unclear about what happens if you get caught outside in the rain.
