  A series of experiments for steady state rotation of water in vessels of
various geometries is presented. The experiments focus on the geometrical
characteristics of the rotating liquids and the change in their surface
topology, from that akin to a sphere to that of a torus (i.e., from genus 0 to
1), for sufficiently large angular speeds. Cylindrical, planar rectangular,
cubic, spherical, and conical containers are considered. The cone is an
exception as some liquid always remains in its apex, no matter how fast the
spin. It is shown also that for any amount of liquid within, there exists a
critical angular speed above which the liquid can no longer be confined and is
therefore expelled from the cone spontaneously breaking the symmetry. This
instability is investigated experimentally.
