The idea for Velcro, conceived by George de Mestral, occurred whilst out walking his dog. Burdock seeds were always getting caught in his dog’s fur as she ran through the fields. De Mestral, an engineer, inspected further, and found the seeds hooked onto the fur with a series of microscopic loops. And so Velcro was born. It would go on to be used extensively, from children’s trainers to boots for the moon landing. Good dog.
