Experimenting On Sound

Yesterday I made a string phone out of cups and strings. To make my string phone work, I had to make sure that I pulled the string tight enough. Then I would give one of the cups to my friend so I can talk to her/he through the string phone. After I put the cup on to my ear and listen to what my friend is saying through the cup. That is how my string phone works.
