The finger whistle may seem difficult, but with a little practice, anyone can master it.

To complete this How-To you will need:

Clean fingers
A mouth
A mirror

Step 1: Position fingers

Form a U shape with your thumb and forefinger or middle finger.

Tip: Use a mirror to perfect your form and technique.

Step 2: Place in mouth

Place your fingers partly inside your mouth, wrapping your lips tightly across your teeth. Only the outer edges of your lips should be visible.
