  It was argued recently that, in general, an arbitrary induced theta vacuum
state would be created in the heavy ion collisions, similar to the creation of
the disoriented chiral condensatewith an arbitrary isospin direction. It should
be a large domain with a wrong theta orientation which will mimic the physics
of the world when the fundamental theta is non-zero. I suggest a few simple
observables which can (hopefully) be measured on an event by event basis at
RHIC, and which uniquely determine whether the induced theta vacuum state is
created.
