tin can telephone
Playground voice wire
A tin can telephone is a simple communication device made by connecting two cans or cups with a taut string, allowing sound vibrations to travel between them.
Children often make these as science projects to demonstrate how sound waves can be transmitted through a medium.
The phrase sometimes appears figuratively to describe primitive or unreliable communication methods.
We made tin can telephones at summer camp.
