Phonograph
The first phonograph was invented in 1877 at the Menlo Park lab. A piece of tin-foil was wrapped around the cylinder in the middle. You shouted a short message into the piece on one side of the cylinder while you turned the handle. Inside this piece was a needle. Your voice would make the needle shake, or vibrate. The sound vibrations would go through the needle and make a line, or groove, into the tin-foil. A needle on the other side could play back what you had just recorded.
