Do you know that you can hear musical noises from a coat-hanger?
　　
　　If you want to hear them, you must tie a metal coat-hanger to the centre of a piece of rope a metre and a half long, as shown in the picture. Now you understand what you must do next. You tie one end of the rope three or four times round your left finger, then the other end the same way round your right finger, and put the ends of your fingers into your ears.
　　
　　Now you come up to a chair and allow the coat-hanger to strike against it. You will hear with surprise some beautiful music, like the music of a large bell or of an old clock.
　　
　　You hear the music because the coat-hanger vibrates. The rope and your fingers bring the sound waves to your ears.
