Very interesting and detailed explanation of sinking mercury vapor. Could you please explain to me the rising mercury vapor seen coming off the liquid mercury in the carpet and the dish in videos presented on this site?

Thanks
I hate to tell you, but mercury vapour does rise. There's no question of that. Yeah, check out the videos the previous poster added. It also appears to me that in the smoking teeth video there was a fan running lightly so that you'd be able to see the vapour moving. Might have been done to make it look more sensational, but it's still just moving it around.
Below is the response I got from my friend, Sam Queen (one of the country's leading experts on mercury). Perhaps the experts at Quackbusters should do more research before such condemnations.
In this case, you need look no further than the routine used by OSHA when
assessing exposure to mercury vapor. OSHA NEVER looks for mercury vapor on
the floor, unless in a refrigerator. At room temperature, which is typical
of the workplace, they would always test the vapor at higher points within
the room, due not only to the fact that this is where breathing takes place but also that mercury vapor rises. I'd like to see their response to this information. Sam
Nice try, Doc. Just a bunch of scientific-sounding bs designed to obfuscate and obscure the truth. So why does the density of the vapor increase whenever the tooth is abraded with an eraser or hard instrument? Is a dental pick made of ice? It should also be noted that the fluorescent screen is warm and is inducing an upward thermal air current. So all of your high-sounding lingo about the density of mercury vapor is just smoke and mirrors.
The fan creates a draft and the light is warm, creating a thermal current. No big mystery here, regardless of the relative density of mercury vapor.
They never mentioned the room temperature. I think the direction of vapors would likely vary depending on room temperature more so then the tooth or water temperature. The duck is calling someone a quack! lame
Re: "I think the direction of vapors would likely vary depending on room temperature more so then the tooth or water temperature. The duck is calling someone a quack! lame"
Sounds like you're the lame duck. I personally have never seen a light source that operated at a temperature COLDER than room temp. Have you? You're deliberately obfuscating the truth.
If I were handling mercury and were convinced of its hazardous status, (As this handler seems to be) I'd be doing so in a vented hood, "fume cabinet", or some other enclosure that most serious science labs have just for this purpose. The volume and speed of the air being drawn into this protected area would far outdo any effects of higher OR lower vapour density. . . Most vented hoods draw air UP !
It would be fairly easy to replicate this with a wet tooth without fillings wouldn't it? Would someone less lazy than me like to try? 
I know, the people who put this video out can put up or shut up and replay the experiment, under controlled conditions with a bunch of different teeth in all sorts of conditions and restorations. Then, real scientists can stand to one side with a legitimate mercury detector and see what those fumes really are. For proof positive that mercury is killing us, replaying an old tape over and over is pretty weak.
Same idiotic argument has been used to conclude that CFC's can't get to the ionosphere. Being large, they should all be down here on the floor, so people couldn't have been responsible for the destruction of the ozone layer. Morons. By that logic, all the ozone should be down on the floor too.
Gravity is a very small force in relation to the time scales we are talking about, the masses we are considering, and the velocities of particles at or near room temp.
In any case, there are a dozen ways of showing the same thing. You can chew gum and exhale into a breathalizer; you can put the filling in a right angle glass tube, with the other end of the tube in liquid nitrogen, measuring after a time the amount of Hg that has condensed in the cold end of the tube; you can do electron micrographs of the surface of amalgam fillings, with which you discover mercury droplets on the surface....
It's truly stupid that we're still arguing about this.
Forget the ozone layer: REPLAY THE EXPERIMENT, under proper conditions! This is not unlike the seers who claim to be able to speak to the dead but are unwilling to prove their claims under controlled circumstances with James Randi supervising. What's so hard about redoing the experiment? How do I know that the tooth wasn't treated with some chemical or that it had a filling at all?
Mercury DOES leak out. This is an established fact. But it's also an established fact, through proper experiments (not magic tricks), that one would need about 800 filled surfaces to even begin to feel sick.
Do a search on youtube on "mercury vapor" and sort by "date added" - you'll find video evidence that rising vapors from warm objects can be faked using the schlieren technique.
Very nice explanation for water, but what I wanna know is how you explain the rubbing and the burning of the tooth producing vapours?
It's all very easy to debunk "quacks" by loosely grasping a part of science and using it to draw the conclusion you were trying to draw - the same thing that the "pragmatic", scientific community like to accuse everybody else of doing. Science is no less guilty than anyone else of ignoring evidence that contradcicts the desired situation and exaggerating all others.
Even if the video was exaggerated - WHY would you let someone hack away at your tooth and fill it with a poisonous metal???
"Even if the video was exaggerated - WHY would you let someone hack away at your tooth and fill it with a poisonous metal???"
Yes, all the other filling options don't have "poisons" in them. The only difference is that the deadly, brain-damaging elements in the other "safe" fillings all have seventy five syllables and no one without an advanced degree know what they are. But silver fillings have MERCURY OH MY GOD MERCURY THE MOST DANGEROUSEST METAL KNOWN TO MAN EVER IN THE WORLD MERCURY MERCURY MERCURY.
