This video is specifically for people who want to learn how to whistle very quickly. The young guy in the video instructs you how to whistle by putting your two middle fingers in your mouth at the same time. First before blowing air through them, you must wet them with tongue or with water. Next step is you blow really hard and through the space in between the middle of your fingers which are placed at the edge of your mouth, next to your jaw. This will allow you to whistle very loudly. This easy step by step guide will teach you how to whistle even if you never learned!
