In order to make these, you must stand in the corner of the room, near
a mirror. Let some one hold a light behind you, so that the shadow of
your head and shoulders will be thrown upon the wall, and also that
the reflected light from the mirror will fall at exactly the same spot
as the shadow of your head.
If the mirror is now covered with a piece of thick paper, from which
two eyes, a nose, and a mouth are cut out, the effect shown in the
drawing will be produced. In order to make the shadow still more
lifelike, cut out two pieces of paper, fasten one over the mirror, and
move the other over it. In this way the eyes and mouth of the shadow
may be made to move.
