Transcribed Image Text:Do Hands Adapt to Water?
Researchers in the UK designed a study to determine if skin wrinkled from submersion in water performed better at handling wet
objects.¹ They gathered 20 participants and had each move a set of wet objects and a set of dry objects before and after submerging
their hands in water for 30 minutes (order of trials was randomized). The response is the time (seconds) it took to move the specific set
of objects with wrinkled hands minus the time with unwrinkled hands. The mean difference for moving dry objects was 0.85 seconds
with a standard deviation of 11.5 seconds. The mean difference for moving wet objects was - 15.1 seconds with a standard deviation
of 13.4 seconds.
