Wind Instrument
How It Works
This is a musical instrument. To hear its sound, we have to gently slide the bent tube (yellow) upwards so that it just touches the balloon. Simultaneously we have to blow air through the thin straw when a loud and clear sound will be heard. If we now change the position of the bent tube, a sound of another note will be heard. At each note we can hear two sounds by pressing the holes in the bent tube. So it covers all the notes of music.
