Why can't I hear any thing even if someone whispered to one of the match box when the thread connecting it is slack?

Solution

In this activity, your voice vibrated the air inside of the box, which in turn made the bottom of the box vibrate. These vibrations were transferred to the string and then into the bottom of your partner's box, which made the air inside of his or her box vibrate and become detectable sound. When the string goes slack, the vibrations dissipate more easily and get lost along the way. (Landline phones work on the same idea but they transfer the sound waves into an electrical signal, which can travel even farther over wires—and the landlines don't have to be kept taut.)
