Required: Two tin cans, a length of string. A small hole is made in the bottom of each can large enough for the string diameter. The string is pushed through the hole in bottom of each can and a large knot tied to prevent it from pulling back through the hole. when the string is kept taught between the cans, it is possible to transmit and receive sounds from one can to the other via the taught string. The string acts as a mechanical sound conductor. Increased efficiency can be achieved by substituting suitable wire for the string.
Of course if you want to cheat - just use your I-phone!
