How Sulfur Hexafluoride Changes The Pitch Of Your Voice

Many of us know that when you inhale helium, it will raise the pitch of your voice. This has been the source of fun and laughter for all ages for a very long time. Did you know that there are other gasses that have similar effects on your voice?

Sulfur hexafluoride has the opposite effect of helium – it makes your voice very low – and it’s equally as funny. Sulfur hexafluoride is a gas that is six times heavier than the normal air that we breath. If you breath in helium (which is about six times lighter than the air we breath), the pitch of your voice goes up. However, if you inhale sulfur hexafluoride (which is about six time heavier than normal air), the pitch of your voice will become low. Watch the video below from MythBusters to hear it in action!
