How a simple coat hanger can reveal the hidden physics of sound
In short: Discover how a metal coat hanger and some string can demonstrate how vibrations travel through solids. This simple home experiment helps children explore the science of sound and the concept of variables through play.
By tying string to a metal coat hanger and placing your fingers in your ears, you can hear a fork tapping the metal much more loudly. This occurs because vibrations travel through solid metal and string more easily than they do through the air.
This activity, featured by The Royal Institution, serves as an introduction to how changing one variable can affect another, encouraging children to investigate the world around them.
