Whistling Loudly With 2 Fingers

Okay we all want to learn how to whistle. It's a funny trait.
Materials:Clean hands, and a mirror (optional)
1. Now you need to chose your finger combination. You can either use your thumb and your index finger (same hand), both index fingers, or both pinkies.
2. Now take your fingers and form a V shape and put them on your tounge and Blow!!!
3. It might take a while...It took me over a week to master it. 

Now have fun!!!!!!!!!!!!!!!
