Bubbles that break rules: A fluid discovery that defies logic

A team led by researchers at UNC-Chapel Hill have made an extraordinary discovery that is reshaping our understanding of bubbles and their movement. Picture tiny air bubbles inside a container filled with liquid. When the container is shaken up and down, these bubbles engage in an unexpected, rhythmic "galloping" motion—bouncing like playful horses and moving horizontally, even though the shaking occurs vertically.
