Difficulty: Moderately Challenging
Step1
Clean out your mouth. This isn’t icky, it is just good advice. You get much better air flow when you aren’t wrestling with bits and pieces of whatever in there.
Step2
Take a sip of something. It is easier to whistle when your chops are moist.
Step3
Using your strong hand, form a V with your index finger and little finger. Tuck your two middle fingers up inside the V; it’s not part of the process, it just keeps them out of the way.
Step4
Bend the V forward over your palm so you can touch your thumb to the point of the V. You’re not going to use your thumb, but this helps you create the right angle for your fingers. If your hand now makes a good duck shadow puppet, you’ve got it.
Step5
Push your tongue forward and try to bend the tip upward toward the roof of your mouth. Suck your lower lip over your bottom teeth to create a smooth, firm platform.
Step6
Place the tip of the V against the tip of your tongue, resting your fingers and hand on your folded-over lip. Push your top lip into the open part of your finger V. It’s not pretty or elegant, but it works.
Step7
Firm up everything--fingers, tongue, lips--and blow down through the opening in the V with a hard, fast huff.
