Where did velcro come from, and how does it work? 👟 Velcro works using two strips of fabric: one with tiny, stiff hooks and the other with soft, flexible loops. The strips stick together when pressed and separate when pulled apart, a design inspired by nature. It was invented by Swiss engineer George de Mestral, who came up with the idea after a walk in the woods with his dog in 1941, when he noticed how burrs clung to their clothes and fur! #science #physics #engineering #technology #knowledge
