Sulfur Hexafluoride vs Girl (Anna Spitz)    by James Lincoln and Anna Spitz

These two videos we made to feature some of the demonstrations that can be done with Sulfur Hexafluoride.

The first was made by James Lincoln as part of a video contest and the second was made by James Lincoln and Anna Spitz as part of a video demonstration series.

Sulfur Hexafluoride is available from Flinn Scientific, and should only be inhaled from a balloon, as should helium, and never from the bottle directly.

Sulfur Hexafluoride Deep Voice Gas by Steve Spangler Science

Spangler does the voice demo, and floats a boat on it, as well as show that SF6 prevents sparks.
