Question

if you have a long string and two cans and attach both cans to the end of the rope, would it work if you talked to someone through it? and what's it called??

Answer 1

it does work but purely through vibrations , you carnt actualy hear what the other person is saying.especialy if there more than about 10 meters away. and the string is ment to be wet.

i think its called 'tin can phone'x

Answer 2

A home-made telephone.... The sound waves travel along the string and you can make out what they are saying on the other end.
