Scientist of the Week-Phone a Friend

This week's scientist of the week showed us what we could do with a piece of string that was 12 feet long and two cups. He made a phone! He poked holes in the cups at the bottom and then he tied a long piece of string through the cups. Once you pull it tight, you can talk through it. He explained that it worked because when you talk, vibrations go down the string into the other cup.
