yes, i just got her to switch, not by looking besides her in my periphery (i suppose by tricking the brain at instant of relative easy, but by varying focus:
in cricket you catch the ball with 'soft' hands, i.e. you relax slightly in the wrist and into the impact-receiving hands, and give just a little right upon the moment of impact, thus absorbing all moment of the object
try catching the top foot with soft eyes where you know it will return, and then just hop on and hitch a swirl on the lady's hey ho lovely toe, i got lucky at third attempt and was soon able to switch to and fro
this can also be performed in the (top) center of the movie, where the switch seems to be initiated
