Question: If I use yarn for my tin-can telephones, then why do I hear the things the other person is saying so clear? why is yarn the best string for the tin-can telephone?I mean why does it work so good? Please answer this question. My project is due on May 15th. Which is Monday. Any suggestions are appreciated.Thankyou.

Answer: We missed the deadline. Don't you just hate it, when all around you fall silent. When I was a kid, our tin-can telephones only seemed to work if we were in the same room and hollering, but maybe we weren't using the right kind of yarn.\n\nI found this on line: \n\nAmanda, age 11 of Ossining, NY wrote:\nI used two coffee cans and a cotton string. I could actually hear the other person though the can. I did not think a string could actually carry sound. I think the longer the string, the better.\n\nBrianna, age 12 of Virginia Beach wrote:\nI did it with a small string and it worked great. I first did it with a thick one, and it didn't go so well.\n\nJonathon, age 12 of Rockledge, FL wrote:\nI was absolutely amazed at what we could do with these things! We tied about 15 strings together in the middle and put cups on all the ends and it worked!\n\nAdilene, age 12 of Perris, CA wrote:\nWhen I did this I was so suprised because my brother and I did a telephone string from his room to mine. That was so cool.\n\nAlexandra, age 6 of Old Town, ME wrote:\nWe used plastic cups and tin cans, and yarn and string. We did plastic cups first, with yarn then with string. Then, we did tin cans with yarn, then tin cans with string. The tin cans, with string or yarn, were not so good. The plastic cups with yarn were better. The plastic cups with string were the best.\n\nDanin & Margaux of Marco Island, FL wrote:\nOh my goodness! Well, we are in 8th grade and our assignment this month was to create an experiment/project on sound. It might seem kinda funny for teenagers reaserching on Zoom, but it worked! We did our experiment and out final conclusion was that cotton string and plastic cups worked the best so far. Tomorrow we will try aluminum cups. We just wanted to say thanks to Zoom for helping us with our project!!!\n\nHallie, age 8 of Verona, NJ wrote:\nWe used tin cans w/nylon string. We couldn't hear anything. We then used plastic cups w/plastic cord, we could hear some noise. Finally we tried plastic cups with cotton string. This worked the best. Each string was about 3 feet long in between 2 rooms. It was amazing results. Thanks for the help.\n\nJames, age 14 of Tallahassee, FL wrote:\nI used a string, tube, and a wire to see which one worked best. It was the tube.\n\nKallie, Sarah, & Melissa of CT wrote:\nWhen we put the string through the cups and pulled tight, we could hear the other person from 10 feet away. It sounds like an echo and really felt like a real telephone. We did it without the paperclips and just use a knot.\n\nToby, age 5 of Attica, NY wrote:\nWhen you talk you have to keep the string taut and then you can hear.\n\nLucenith, age 12 of Lowell, MA wrote:\nString telephone really worked I mean now I can talk to my friends with out making a bill... Me and my friends made up a game called telephone bill with the string telepgone and you have to make your own money and if you forget to pay the other person have to cut the string!!! And if you pay it you'll get your line back. But it only works if your friend lives next to you.\n\nErin, age 10 of Franklin, TN wrote:\nIt worked but it does not work unless the string is pulled as far as possible.\n\nMisael, age 8 of Tulare, CA wrote:\nThe string telephone worked very well between two rooms.\n\nEvelyn, age 9 of Dallas, TX wrote:\nI poked a whole in two plastic cups, and I put a string through the holes and tied a knot. Then my friend and I could talk and hear the words we were saying.\n\nBrianna, age 8 of Lake Stevens, WA wrote:\nWhen the string was to long I could not hear my friend at the other end of the string. We tried three feet and it worked perfectly. Maybe next time we'll try four or five feet.\n\nRenee, age 12 of Atlanta, GA wrote:\nIt really worked we tried to do it with four cups and it worked.\n\nDeverial, age 15 of Houston, TX wrote:\nIt was so cool And I'm Still in shock! Thanks for leting me know how to do it.\n\nLulu, age 11 of Beverly H
