A team of researchers led by a physics graduate student at the University of Massachusetts Amherst made the surprising discovery of what they call a “shape-recovering liquid,” which defies some long-held expectations derived from the laws of thermodynamics.
The research, published in Nature Physics, details a mixture of oil, water and magnetized particles that, when shaken, always quickly separates into what looks like the classically curvaceous lines of a Grecian urn.
“Imagine your favorite Italian salad dressing,” says Thomas Russell, Silvio O. Conte Distinguished Professor of Polymer Science and Engineering at UMass Amherst and one of the paper’s senior authors.
