Because sound is caused by the vibration of air. When air is caused to vibrate by blowing across the bottle top sound is formed.
there is a little energy used, the point is you simply convert a wind energy into a sound energy. remember you cant create any kind of energy.
The whistle works by causing the smooth flow of air to be split by a narrow blade, sometimes called a labium or windcutter, creating a turbulent vortex which causes the air to vibrate. The length of the chamber typically defines the resonance frequency.
Onomatopoeia
A whistle typically produces a high-pitched sound, while thunder is a deep rumbling noise.
When blowing a whistle, the energy that is wasted is primarily in the form of sound energy. As air is forced through the whistle, it vibrates and produces sound waves, which dissipate into the surrounding environment as noise. Some energy is also lost as heat due to friction and air resistance as the air passes through the whistle's chamber and creates turbulence. Overall, the majority of the energy input into blowing a whistle is converted into sound energy and dissipated into the surroundings.
You blow your fingers in your mouth.you can blow with a real whistle.when you whistle you blow loud.

Blowing the whistle is calling attention to wrong doing.
To blow a whistle, put your lips together and blow air through them while holding the whistle in front of your mouth. The sound will be produced by the air vibrating inside the whistle. Make sure to adjust the pressure and intensity of your blowing to control the pitch and volume of the whistle sound.
