Strategy:

         (1) Each of the volunteers will pick up a mirror.
         (2) One of them will go out and stand by the outside door so that 
            he/she can use the natural light as light source.  The other
            person will stay inside the auditorium in a way that both of
            you can see each other.
         (3) Turn off the light in the auditorium.
         (4) The person outside will hold the mirror up to make a light
            beam so that the light beam will hit right on the person who is
            holding a mirror inside the auditorium.
         (5) The person inside will hold the mirror up so that his/her mirror
            can use the light beam which comes from outside to make another 
            light beam and hit the screen inside the auditorium.
