So far I leanrt changing pitch using staw. One thing that I was interested in was how the tin can telephones worked. When you tighten the wire you will hear your friend more clearer and also if you block your other ear.

    I would love to do what you did with those tin cans with one of my friends. I've also seen people doing it on television. If you could, can you please tell me and my class how you did it?
