9. Velcro
In 1941, Swiss engineer George de Mestral was hiking in the Alps with his dog when he noticed burrs from the burdock plant clinging to his clothing and his dog’s fur. Curious about how these burrs adhered so tenaciously, he examined them under a microscope and observed hundreds of tiny hooks on their surface. Inspired by this natural mechanism, de Mestral envisioned creating a two-sided fastener: one side with hooks and the other with loops. After years of experimentation, he patented the hook-and-loop fastener in 1955, naming it “Velcro,” a combination of the French words “velours” (velvet) and “crochet” (hook). Velcro revolutionized fastening systems and is now ubiquitous in products ranging from clothing and footwear to aerospace equipment (smithsonianmag.com).
