What Does Helium Actually Do to Your Voice?

In this video I show you a whirly tube and how it works and use it to show you what helium does to your voice and wind pipe. I talk about how helium doesn't actually change the pitch of your vocal chords, but rather of your vocal tube, and this changes the timbre or sound quality of your voice instead of the pitch.
