  We discuss a simple and experimentally available realization of fracton
physics. We note that superfluid vortices form a Hamiltonian system that
conserves total dipole moment and trace of the quadrupole moment of vorticity;
thereby establishing a relation to a traceless scalar charge theory in two
spatial dimensions. Next we consider the limit where the number of vortices is
large and show that emergent vortex hydrodynamics also conserves these moments.
Finally, we show the motion of vortices and of fractons on curved surfaces
agree, thereby opening a route to experimental study of the interplay between
fracton physics and curved space. Our conclusions also apply to charged
particles in strong magnetic field.
