Furry mammals can shake themselves 70 percent dry in just a fraction of a second.
Small animals may trap substantial volumes of water in their fur for their size. For example, when emerging for a bath, a person carries one pound of water. A rat, however, carries five percent of its mass and an ant three times its mass.
“We hope the findings from our research will contribute to technology that can harness these efficient and quick capabilities of drying seen in nature,” says Georgia Tech mechanical engineering graduate student Andrew Dickerson, who led the project.
