This stuff is called SF6 gas and is heavier than air....found in high voltage switch gear, medical device testing and used in some breathing apparatus fit testing.

More information on SF6
here is some more information on SF6.
Super SF6 (Sulfur Hexafluoride) is an inert, non-toxic gas with excellent physical properties, including dielectric, cooling, insulating and arc quenching capabilities. With its unique physical properties, Concorde Super SF6 is ideal for applications such as: electric utilities, magnesium casting, sound insulation, semiconductor etching, nuclear accelerators, scientific and medical instrumentation and more.
Mass Content of Sulfur Hexafluoride (SF6) (%)99.95
Oxygen (O2) 100 ppm vol.
Nitrogen (N2) 250 ppm vol.
Water (H2O) <5 ppm vol.
Hydrolyzable fluoride, expressed as HF 0.3 ppm vol.
Carbon Tetrafluoride (CF4) 100 ppm vol.

Here is another video of sulphur hexaflouride. I am using both of these videos in a haz-mat class to demonstrate vapor density.
