Hold your non-dominant hand still.
Rub your dominant hand on top of your non-dominant hand using a
counter-clockwise movement (about one and a half rotations).
Don't "twist" your hand. The movement is in the shoulder and elbow,
not in the wrist. Keep your wrist immobilized and do all of
the movement with your shoulder and elbow.
LOCAL / "in the immediate vicinity"
