Velcro

He named the invention Velcro, combining the French words 'velours' (velvet) and 'crochet' (hook) to reflect its structure. | He noticed the burrs were covered with tiny hooks that could latch onto fabric loops and fur firmly. | However, their performance turned out to be outstanding years later! | Swiss engineer George de Mestral once returned from a hike with his dog and found many burrs clinging tightly to his trousers and the dog's fur. | This natural mechanism inspired him to create Velcro, a fastener with hooks on one side and soft loops on the other.
