Diamond Theft
There is a famous diamond displayed in a room that measures 15 meters by 15 meters by 15 meters. The room is made entirely of concrete blocks and the floor is covered with a thick carpet. The only thing in the room is the diamond that is housed under a glass cube. The glass cube stands on a one-meter pedestal in the centre of the room. Alarm wires spaced eight centimetres apart and running parallel to each other lie under the carpet. The alarm will trigger if more than four kilograms of pressure is applied to any individual wire. Will Carlo who weighs 74 kilograms was able to steal the famous diamond using the following equipment: a five meter 2 x 4 board, four leather straps (each two meters long and five cm wide), a hammer, and a saw. How could he do it without triggering the alarm?
Answer
Will Carlo stole the diamond in the following manner: First, he cut five meter 2 x 4 boards in half. Then using the available straps, he fastened the two boards to his feet like skies. With the boards strapped to his feet, his weight was displacing enough so that he did not exceed the wire's weight tolerance and triggers the alarm. Carlo then slowly and carefully walked to the centre of the room, smashed the glass cube with the hammer, took the diamond and returned the same way he came in.Hide Answer Show Answer
