Steve Harvey and Miss USA Kára McCoullough Inhale Balloon Helium Together

If there’s one thing we learned from Miss USA Kára McCoullough, it’s that science is fun!

Who knew sulphur hexaflouride makes your voice lower.

Sulfur hexafluoride is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas. Sulfur hexaflouride or SF6, also known as a Deep Voice Gas, is an excellent electrical insulator. SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom, and is a hypervalent molecule, which is a molecule included in a group of molecules that contains one or more main group elements apparently bearing more than eight electrons in their valence shells.
