Talking answer

Rrrring, rrrring, rrrring. It's a telephone made from string.

Materials Needed


two plastic cups
some string
paper clips
sharpened pencil for poking holes


Instructions


With the pencil, carefully poke a small hole in the bottom of each plastic cup.
Tie the paper clip to one end of the string.
Thread the other end of the string through the hole in the bottom of one of the cups. Be sure to thread it from the inside of the cup. The paperclip will keep the string from going all the way through the hole.
Then thread the string through the hole in the second cup, but this time do it from the outside of the cup.
Tie the second paper clip to the other end of the string. The paper clip should be inside the cup, just like the first paper clip.
Then, pull the cups so that the string is tight and have one person talk into the cup while the other person holds the cup to their ear.


Now it is time for you to experiment. Think of a question you want answered. Like, what is the farthest distance you can get the telephone to work using string? Would the sound go farther if you used empty soup cans instead of plastic cups? What about using two different sized cups? Make a prediction. Then change one thing-that's the variable-and test it out. Be sure to tell us what you thought was going to happen and what actually did happen. When you're done, send your reports to our special feedback area. Every week we'll post new results from ZOOMers' string telephone experiments.
