Whether on shoes, caps, jackets or cable ties, in industry, medicine, or in cars, the hook and loop fastener is used everywhere and it is now difficult to imagine our lives without it. A Swiss engineer had the idea one day in about 1941, after taking his dog for a walk. He removed the burrs clinging to his dog‘s fur and placed them under a microscope, where he discovered that there were little hooks on the burrs. Great Inventions tells the story of how this versatile “sticky” material was invented and tests the strongest hook and loop fasteners in the world.
