It seems like the charges move slower in the droplet than they do in the liquid. This leads to charges accumulating on the surface, creating a dipole moment. But this dipole is oriented in the "wrong" direction, leading to instability. The dipole tips over in a random direction. The viscosity means that the droplet starts slowly rotating in that direction.That triggers the dipolization process again, trying to recreate the "wrong" dipole by moving charges. The bulk of the droplet rotates in one direction, while the charges are moving in the opposite direction.
