Tom Smulders of Newcastle University Institute of Neuroscience, explains in this video how the wrinkles that we get on our fingers or toes, after a extended period of time soaked in water, can help to hold wet objects better.
Nonetheless, it is known that this process is controlled by the nervous system, and therefore it seems likely to serve some kind of function. This study carried out with Kyriacos Kareklas and Daniel Nettle, reveals that people are faster at moving objects taken out of water if their fingers are wrinkled than if they are not.
