Sulphur Hexafluoride Flooded Vocal Cords
« on: January 18, 2007, 04:33:13 AM »
We've all heard the high pitch voices from inhaling Helium. But, I've never personally seen how one sounds when you inhale a heavier MW gas. Luckily youtube is here to the rescue.

If anyone has a video with some volatile xenon compounds, please let me know!

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Quick fix for that low voice would be breathing helium (respitory failure ensues).
Sulphur hexafluoride has some nice properties. Like other heavier than than air gasses (eg. Argon) it can be trapped inside open top container and it stays there for quite a time. Sulphur hexafluoride is dense enough to float a boat made of tinfoil.

That's so sweet. I especially like the aluminum foil floating in mid air.

By the way ATMyller, the video Mitch also includes that short video you posted.

Seen this in person!  The guy did helium first, then sulfur hexafluoride.  Quite a contrast.  He was a little lightheaded afterwards.

Are those guys Bored Professors, PhD students or just random people who break into Chemistry Labs?
