Israeli engineer and systems developer Izhar Gafni has invented a cardboard bicycle that’s strong, waterproof and costs less than £10 to manufacture (+ movie).
Izhar Gafni started developing the Cardboard Bicycle three years ago. “Since there was no know-how with regards to the cardboard material, the first two years were devoted to learning the properties and behaviour of the material,” explains Gafni.
“The idea is like Japanese origami,” he says in the movie. “You fold it once and then it doesn’t become twice the strength, it’s almost three times the strength. So I took it from there and did the same thing with cardboard.”
After the shape has been cut out, the cardboard is treated with a waterproof and fireproof coating specially created by Gafni, before lacquer paint is applied over the top.
