George de Mestral invented Velcro in 1955 after examining cockleburs under a microscope during a 1941 hunting trip. His biomimicry insight became one of the most widely used fasteners on Earth.

Spider silk is tougher than steel and Kevlar by weight — yet a spider produces it from liquid protein at room temperature in milliseconds, no factory required.

Silk comes from a caterpillar that spins a single filament up to 1,500 metres long, eats almost nothing but mulberry leaves and can no longer live in the wild. That biology, not marketing, is why silk costs what it does.
