In 1877, Thomas Edison invented the phonograph. It is made using a needle and cone. Vibrations from a recorded record and the needle are broadcast through the cylinder for everyone to hear. Many types of phonographs can be created at home. This is an easy project that can be made with a few household items.

Put the pencil through the hole in the record. Wrap tape around the pointed end of the pencil. Keep wrapping it until it is thick enough that the record won't slide over it. Point the pencil down and turn it. If it is done correctly, the record will not turn independently from the pencil.
Roll the paper into a cone and tape it along the seam to close it. Insert the pin at the end of the paper. It should point down and slightly away from the cone.
Put the pointed end of the pencil on a table so that the record is parallel to the table. Place the pin on one of the grooves of the record and gently hold the paper cone. Start to spin the pencil clockwise so the record starts to play.
