Summary

What controls the way in which a plastic sheet, an old apple, or human skin wrinkles? In their Perspective, Brochard-Wyart and de Gennes discuss the many forms of wrinkling that occur in nature. They highlight a paper by Cerda and Mahadevan (Physical Review Letters), who show how tension and interwrinkle distance are related in macroscopic as well as microscopic cases.
