Pulling the coin out of the eye is very good for small kids/squirmy people, especially after a vanish.

IE Retention, squeeze hand hard, point (With the hand that has the coin fingerpalmed), follow the arm up, and to the eye, produce.

If you know Wither vanish, it's a natural follow-on.

Also: Clean up your room!
