In the school laboratories, kazoos are made to demonstrate that sound can not only be heard but also it can be seen, felt and manipulated to increase or reduce its frequency.
For one to prepare a kazoo, it will require having a cardboard tube paper towel, approximately 7.5cm of square waxed paper, an elastic band, and paint.

Finally, make a hole with a blunt object like a pen at one end of the cardboard below the waxed paper.
When an individual hums into the open side of the kazoo, there are vibrations which originate from his vocal cord that is transferred through the tube making the air molecules to vibrate.
