Key Features: --> The mouthpiece of a whistle is shaped to create a narrow windway. -->The shape of this toy is cylinder. -->length : 6.5 cm -->width :1.3 cm -->It will be available in red ,green and yellow colors. Objective: The thin flow of air is directed against a narrow blade, called a labium (Latin: lip) or wind-cutter. The air stream does not simply split in two, but is unstable and oscillates rapidly back and forth between the two sides of the blade, creating a string of pressure pulses that radiate as sound waves. By attaching a resonant chamber to the basic whistle, it may be tuned to a particular note and made louder.
