Learn how to whistle

I tried this for hours one day, then searched for a video on youtube and had to combine technique from a few different videos. This video is pretty precise on the form and process. It's all about curling your tongue back with your fingers, use lips to cut off all air flow except opening then blow. It's ridiculously loud.
