Steve Spangler Science: Heavy Gas – Sulfur Hexafluoride

This is a gas that can lower your voice to freaky-weird levels.

Chemistry and physics teachers often use a classic science demonstration to show what happens to your voice when sound travels through a gas that’s six times lighter than air. Steve Spangler got to thinking about what happens to that same sound when it travels through a gas that’s six times heavier than air. It’s fun but the demonstration must be conducted by a trained professional. See the Safety Information section below.
