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.
