A man is trapped in a room which is completely bare except for a fire alarm which could have been used to draw attention to his plight if it were not for the fact that the fire alarm?s cable had been cut leaving two lengths of cable dangling from the ceiling. If he can bring the ends of the cables together, he could repair the connection and raise the alarm. Unfortunately, the cables are situated so that he cannot reach one cable while still holding the other. He only has the resources you would normally expect to find in a pocket. How does he solve the problem?
