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.
The hypothesis of a string phone experiment is that sound can travel through a taut string between two cups. This suggests that the vibrations produced when speaking into one cup can be transmitted through the string and heard on the other cup, demonstrating the concept of sound transmission through a medium.
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.

To make a paper cup phone, you will need two paper cups, a long piece of string, a sharp object to poke holes in the cups, and scissors. First, poke a small hole in the bottom of each cup. Next, thread the string through the holes in both cups, tying knots on the inside to secure it. Finally, hold one cup to your ear and have someone else speak into the other cup while holding it to their mouth. The vibrations will travel through the string, allowing you to communicate through the cups.
John K. String the 3rd invented string.why do you ask? huh punk?
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.
