Stretchy joints let earwig wings flip quickly between folded and unfurled. In the first clip above, a simulation captures the way that the springy joints in the earwig wing allow it to crumple in a way that wouldn’t work out according to the strict mathematical rules of origami folding. Researchers used the same approach to design a structure that can lock into either a mostly flat configuration or a bent one.
