The Dog, the Burrs, and Velcro

In 1941, Swiss engineer George de Mestral went bird-hunting in the Alps with his Irish Pointer. When they returned, both man and dog were completely covered in the stubborn, highly annoying burrs of the burdock plant.

Instead of just plucking them off and throwing them away, de Mestral's scientific curiosity took over. He slid one of the sticky plant burrs under a microscope. Looking through the lens, he saw that the burdock was covered in thousands of tiny, elastic hooks that easily snagged the loops of his fabric and the dog's hair.

Realizing he had stumbled onto a genius piece of natural engineering, de Mestral set out to build a synthetic version. After years of testing different materials, he finally managed to recreate the hook-and-loop system using nylon, creating the revolutionary fastener we now know as Velcro.
