Cylindrical container (IMAGE) New York University Caption A recent experimental study, inspired by the super-rotation of the Earth's solid core, shows when turbulence flows contained in a cylinder interact with a free body a surprisingly smooth rotation is observed. The red (warm) and blue (cold) ribbons represent water flows. Credit Image by Kaizhe Wang and Jun Zhang.
