NARRATIVE
            There is a clock which shows time in minutes, seconds, and hundreths of a second. It is also hooked up with a light bulb to measure the reaction time of a student.

            Plug the clock into a switched outlet so that when the instructor switches on the power, i.e. starts the clock and turns on the light at the same time, the student will then shut it off with his button.
