By magnetically levitating water droplets, and using a “liquid electric motor” technique to spin them, researchers can investigate how the droplets change shape. Rather than being just a curious experiment, the results could provide insights into systems that cannot be controlled in the laboratory, such as black holes and atomic nuclei.
