Nice find. I wonder where I can buy that gas?

Loses a point for bad editing. Gains it back for flagrant abuse of funding.

Mr. Science doesn't advocate sucking.

Why did I always get the joyless, humorless teachers for science?

They should replace the entire atmosphere with this so we can all talk badass.

I once got lucky enough to see Jay Leno do this on his show.

Wheeee!!!!

SCIENCE!!!

We had a leftover cylinder of this stuff in a lab where I was a post-doc. I demoed it for grad students for a laugh.

Also fun SF6 fact: it has a global warming potential of 23,900 times that of CO2. Most of it is from leaks in high-voltage switch gear and equipment. I remember a US Department of Energy report where they were able to reduce their greenhouse gas emissions by like 90% over a few years just by eliminating leaks of this "harmless" gas.
