Scientists in Belgium have uncovered a new way to shake things up. Violent bouncing of a water droplet coated with oil causes the oil layer to move inside and fracture into many oily globs. In a paper published in the December Chaos, researchers at the University of Liège in Belgium call this microemulsion of oil and water the mayonnaise droplet.
