To make a can telephone, you will need two empty cans, a sharp object to poke holes in the cans, and a long piece of string. First, poke a small hole in the bottom of each can. Next, thread the string through the holes in both cans, tying knots on the inside to secure it. Finally, hold one can to your ear and have someone else speak into the other can while holding it to their mouth. The sound vibrations will travel through the string, allowing you to communicate with each other.
You could use a shoe box as the base, then use the same size cardboard to cover the hole. Then, you cut a circle out of cardboard as the dial(write numbers on it.) For the telephone parts, fold a half sheet of paper for both parts. If you want to make one that's not tacky, you're on your own.
Telephone cords are coiled to prevent tangling and to make them easier to store and handle. The coiled design allows the cord to stretch out when needed and then retract back into a compact form when not in use.
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.
To make a telephone using cups, you will need two cups, a long piece of string, and a sharp object to poke holes in the cups. 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 and talk into one cup while the other person listens through the other cup. The vibrations of your voice will travel along the string, creating a simple telephone system.
Sound energy is transferred when speaking into a telephone. The vibrations caused by the sound of our voice are converted into electrical signals that are then transmitted through the telephone line to the receiving end.
