How to Whistle loudly using only 2 fingers
Carla Simian demonstrates how to whistle loudly using only two fingers. Whistling with two fingers is an easy way to get the attention of people who are far away from you. Whistling with two fingers is easy with a few simple steps and some practice. First, fold your tongue backwards so it presses against the bottom teeth. Make two fingers in the shape of a V and place them on your tongue. Next, put your lips tight around your fingers and blow. Adjusting the angle and the depth of your fingers, you can create a powerful whistling noise to attract attention.
