We obviously counter steer all the time, but a lot of us don't realise it. Your suggestion is a good way to demonstrate what's happening, but can you explain the physics behind it??
Or an easier way of feeling the countersteer is to find a straight road, ride along at pace, and swerve the bike left and right gently. You'll feel the effect of pushing left to go left (and right to go right) easily then.
