[TheForge] a lot of unimpressive BS

Yep, that's what started it.  You're right and wrong.  You're right in that 
"once they cool" they will sink out and they will rise when hot (be 
displaced and forced upwards by denser cooler gasses if we need to be 
technical).  But the discussion was in regards to hot exhaust gasses from a 
propane forge.  That and the fact that your original comment didn't include 
the qualifier "once they cool" and suggested venting close to the floor.

I replied that the hot gasses from a propane forge would rise (into a 
hood), not sink to the floor.  Tom got technical in that hot heavy gasses 
do not rise, they are pushed up by cooler denser ambient gasses.  I then 
replied that details and the mechanism aside, the hot gasses will rise 
(into the hood/vent).  Mike made a tongue-in-cheek comment about my shop 
and venting.

Somewhere along the line the "who said what" has undergone the typical 
e-mail discussion route.  That is, since one can't hear or see "tone of 
voice" in e-mail, some things get misinterpreted and spiral off in unwanted 
and unwarranted directions.  Heck, even this post will probably be taken 
other than with a grain or two of salt.

Shoot, we could even take it further and add in that although some gasses 
are heavier than others, the atmosphere we breath isn't layered.  If it 
were we'd be breathing something other than O2.
