How do you make string telephone?
Take two paper cups and poke wholes through the bottom. Get some string and insert it through the bottom of the cup. Tie knots on the ends of it so it will pull through the bottom of the cup. Then make the string taught and talk into the cup. If pulled taut enough, the string will carry the vibrations of your speech, and your string telephone should work.
How do string telephones work and transmit sound between two people?
String telephones work by transmitting sound waves through a taut string or wire. When one person speaks into the cup at one end, the sound waves travel along the string and vibrate the cup at the other end, allowing the other person to hear the sound. This simple method of sound transmission is based on the principle of mechanical vibrations traveling through a medium, in this case, the string.
Why telephone does not work when a third person touches the string?
The current travels though the person and dosn't reach the other cup.
How do plastic cup phones work?
The string must be pulled taut in order for the phone to work. Longitudinal waves travel through a medium by a process of compression and rarefaction, which in this case alters the tension of the string. If the string is not taut, the alterations in tension will not vibrate the listener's cup. Similarly, elastic strings will not work properly, because the wave will just stretch the string without vibrating the listener's cup. Don't let the string come into contact with any other objects, as this will partially divert the sound wave into the object, causing a weaker signal on the receiving end. Speaking into the cup transmits the sound of the speaker's voice into the bottom of the cup. The bottom of the cup acts as a diaphragm and vibrates with the sound of the speaker's voice. As the bottom of the cup vibrates, it transmits the vibrations into the taut string. The sound travels along the string as a longitudinal wave and ultimately vibrates the bottom of the receiving cup. The cup transmits the sound into the air around the listener's ear, allowing her to hear the speaker. Because the sound travels through solid mediums--the cup and the string--it travels more effectively than through air, allowing the users to communicate across large distances with volumes that would be inaudible if spoken through air
How can I make a cup phone with string at home?
To make a cup phone at home, you will need two paper cups and a long piece of string. Poke a small hole in the bottom of each cup. Thread the string through the holes and tie knots on the inside of the cups to secure it. Pull the string tight and talk into one cup while the other person listens through the other cup. Adjust the tension of the string to improve the sound quality.
What kind of string do you use on cup phones?

Does two cups and a string work?
Yes, two cups connected by a string can work as a basic communication device, often referred to as a "tin can telephone." When one person speaks into their cup, sound waves travel through the string, causing vibrations that the other person can hear in their cup. However, this method is effective only if the string is taut and does not touch any other surfaces, as that would dampen the sound. It's a fun demonstration of sound transmission through solid materials!
