Sulfur Hexafluoride - Deep Voice Gas

It's the anti-helium gas that makes your voice sound like Barry White.


Why does helium make your voice sound like a cartoon character? Chemistry and physics teachers often use this classic science demonstration to illustrate how sound travels through a gas that is six times lighter than air. Steve Spangler looks at the science behind the demonstration and wonders what might happen to sound that travels through a gas that is six times heavier than air.

That was hilarious!

That was really, really funny! Adult newscasters having that much fun on the air is pretty cool. :-)
