When you listen to a sound, you are listening to a vibration that moves and moves through the air. When you make a string phone, you talk to it and it makes the bottom of the glass vibrate and that vibration travels along the string to the other glass where they can hear the sound of your voice coming out of their glass.

Does cup on a string work?
The key is to make sure the rope is tight between the two cups, and this usually means that the distance is limited and the two people need to be connected to each other by a straight line. On the same subject : How to use landline phone. But as long as the string is tight, it works.
What is the best cord for a tin can phone? Of course, they were also running their 650+ foot line. Cotton string, fishing line, and regular twine also work.
Will the lanyard work for cup phones? How does the wired telephone work? A chain phone works much like a landline phone. When you speak to the cup, your voice sends sound waves into the cup, causing the bottom of the cup to vibrate. The vibrations are transferred to the string, through the string, and to the bottom of the other cup.
How can I make my string phone work better?
If the string is loose, the sound is less. This is because the loose string causes vibrations to travel all over the place instead of straight down the string. Try experimenting with different string lengths, string types, and cup types to see which produces the best sound over the longest distance.
Where do the sound waves travel in the string phone? Where do the sound waves travel in the string phone? (Answer: Sound waves travel from the first person’s mouth, into the first glass, down the string, vibrate the second glass, and reach the second person’s ears.)
Do wire phones really work? The old “two cans and a string” (or better yet, “two paper cups and a string”) technique really works. The key is to make sure the rope is tight between the two cups, and this usually means that the distance is limited and the two people need to be connected to each other by a straight line.
How far can a corded phone work? Its maximum range was very limited, but hundreds of technical innovations (resulting in some 300 patents) increased its range to about 0.5 miles (800 m) or more under ideal conditions.

What string is best for a cup and string phone?
You’ll also need yarn, and lots of it! The guys in the 2013 video used nylon twine, which is pretty strong. Of course, they were also running their 650+ foot line. Cotton string, fishing line, and regular twine also work.
What is the best material to use to make the most effective wind-up phone? Having a soft connective material, like cotton string, that has a higher density or number of molecules in a given amount of space than air, can help sound waves move a greater distance.
What type of rope do you use for phone cups? A paper cup telephone requires two cups, a piece of inelastic string, twine or fishing line, two paper clips, and a pencil or sewing needle. To create a paper cup phone, make a hole in the bottom of each of the cups with your pencil or sewing needle and thread each end of the string through each hole.
How does sound travels along the strings?
Because the molecules in a solid are packed much closer together (more densely), vibrations are transmitted much more easily from one molecule to the next. As a result, sound waves travel faster through solids (like a string) than through gases (like air).
How does sound travel? Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium. In sound, the disturbance is a vibrating object.
How does sound travel along a wave? Sound waves move through vibrating objects, and these objects cause other surrounding objects to vibrate, carrying the sound. The further away you are from the original source of a sound, the waves slow down until they don’t have the strength to vibrate any other particles.
