Water organ

A water organ is an old-fashioned music instrument that is made of tubes and pumps. The tubes are filled with water, and they make a sound when air is pushed through them. This sound is then controlled by the organ player who uses a keyboard to push the air through the tubes in a particular order to create beautiful music.

Think of it like blowing bubbles in a cup filled with water. When you blow the air through a straw, the bubbles make a sound. Now imagine that instead of one straw, there are many straws of different lengths and sizes, and they are all filled with water. When air is pushed through these straws in a particular sequence, it creates different sounds, just like pressing different keys on a piano.

Since water organs were invented before electricity, they were powered by human hands or pedals that pumped the air through the tubes. The music created by the water organ was often played in churches and other holy places, where it added a beautiful and peaceful ambiance.

In summary, a water organ is like a musical instrument made of tubes filled with water that creates music by pushing air through them in a particular sequence, controlled by a keyboard.
