How to whistle backwards

You may know how to whistle the regular way, but how cool would it be to do it backwards?

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• your lips
• air
• basic whistle abilities

1. Position your lips like you would to whistle normally, only a little looser.
2. Suck in air at a moderate rate to make the whistling noise.
3. Practice makes perfect. Just like whistling the normal way the more you practice the better you get.

Tips & Warnings

• Try adjusting the rate you pull air in for this whistle, play around with it until you find what works.
• Be sure not to go to crazy with your practicing, do it too long and you'll make yourself light headed!
