tin can telephones
Primitive childhood intercom
Tin can telephones are a simple communication device made by connecting two cans or cups with a taut string or wire.
When one person speaks into their can, the vibrations travel along the string to the other can, allowing a second person to hear the sound.
They are a classic children's project for demonstrating how sound travels through vibration, though they work only over short distances and require the string to remain pulled tight.
We made tin can telephones in science class.
