In 1991, researchers at the University of Cambridge’s Computer Laboratory faced a simple yet persistent problem: finding out whether the communal coffee pot in the Trojan Room was full without wasting a trip.

In the late 1940s, Francis Rogallo, inspired by the idea of simple and affordable flight, and his wife Gertrude created the first prototype of a flexible wing. Using kitchen curtains, they built and tested their design in a homemade wind tunnel, leading to a 1951 patent for the “Flexible Kite.”
