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!
To make a phone using cups and string, you will need two cups and a long piece of string. Poke a small hole in the bottom of each cup and thread the string through the holes. Pull the string tight and talk into one cup while the other person listens through the other cup. This creates a simple communication device using the cups and string.
Poke a small hole on the bottom of two styrofoam cups (make sure that the whole is in the center of the cups), thread a long string through the cups (be sure that the top of the cup is pointing out). Tie a knot at both ends of the string so that the cups will not fall off. When you are talking into the cup, keep the string tight so the person that is listening can hear.
two cups with a piece of string attached to them both.
Nothing, as it won't go anywhere. Only a taut string can transfer vibrations
thats all they had
I would say that plastic cups are better for string telephones because you cant get string through a metal cup.
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.
To make a telephone using cups and string, you will need two cups and a long piece of string. Poke a small hole in the bottom of each cup and thread the string through the holes, tying knots on the inside to secure it. Pull the string taut and talk into one cup while the other person listens through the other cup. The vibrations from your voice will travel along the string, creating a simple form of communication.
To make telephone cups, you will need two paper or plastic cups, a long piece of string, and a sharp object like a pencil. Poke a small hole in the bottom of each cup. Thread the string through the holes, tying a knot inside each cup to secure it. Pull the string tight so the cups are connected, and then talk into one cup while holding the other to your ear to hear the sound travel through the string.

Mainly because the two are utterly unrelated.
To make a telephone with cups, you will need two cups, a long piece of string, and a sharp object like a nail. Poke a small hole in the bottom of each cup. Thread the string through the holes and tie knots on the inside to secure it. Pull the string tight and talk into one cup while the other person listens through the other cup. The vibrations from your voice will travel along the string, creating a simple homemade telephone.
