Also know, do can phones work?
Talking causes little vibrations in the air in front of your mouth, as you can tell by speaking into your hand. This vibration is passed along the string and into the other can. When that can vibrates, it creates vibrations in the air once again and you can hear the other person's voice!
Furthermore, how does a string telephone work? (Example answer: When you speak into the cup, the back of the cup vibrates; the vibration extends into the string, like a push on a slinky; the sound waves, or vibrations, move through the string.)
