We study the dynamics of a spinning sphere whose south pole is in touch with the surface of a still body of liquid. When the sphere is turning fast enough, the fluid rises up the sphere, reaches the equator and is flung out as a fountain of droplets. Although the fountain forms for water a weakly viscous fluid, and for propylene glycol a much more viscous fluid, the dynamical situation is different for each. For flows at mid-latitudes on the sphere, we formulate the dynamical equations for the two liquids in terms of Newton's law in a rotating frame, noting that the Coriolis force plays an essential role in both liquids, and obtain qualitative agreement with observations. We also discuss the possible roles played by other forces.
