Jean et al:


They all spiralled in the same direction, too, and I think it was counter
> clockwise?  Would that be correct in this hemisphere?


The Coriolis force induced by the Earth's rotation, which IS responsible for
air currents in the two hemispheres flowing in opposite directions, is
orders of magnitude too small to force the direction of rotation of flying
ants or the water in toilet bowls.

Wikipedia has a great page explaining the physics behind Coriolis forces:
