Suppose there is a circular metal disk spinning at a constant angular velocity. Now imagine near to, but not in contact with the first disk, there is an identical metal disk spinning at the same angular velocity but in the opposite direction (ie. W1 = -w2) and the surfaces are parallel to one another. What is the total angular momentum? (ignore friction)

total angular momentum? it is zero.
