Not all 'flames' are directed by buoyancy or electric fields.
The flames in a solar flare for example leap well beyond any atmospheric lift or electric field or atomic blast push. Instead they are shown to clearly follow a magnetic field.
The flames of a torch are directed by pressure.

btw, electric fields might be responsible for accelerating the plasma in a solar flare but there's still much data to collect on that subject.
Anyhoo, I was merely responding to David's statement regarding open flames/heat going up so I limited my response to address that specific idea. I didn't want to muddy the waters by bringing up nozzles and flame velocity and stuff.
You could learn something from him.

does not buoyancy imply gravity? Wikipedia/buoyancy, i looked it up, and sho nuff, gravity CAUSES the buoyant force! Harvey explained that [i thought] is that proof? it seems that if someone were to read the Wiki definition of buoyancy, they could find out for themselves!
[..]
The idea of buoyancy was summed up by Archimedes, a Greek mathematician, in what is known as Archimedes Principle: Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object....i copied that part, but the word WEIGHT...that implies gravity? can we say there is a force opposite of gravity? without using the word Buoyant?

Now consider the moon. The moon has gravity but no buoyancy in the ultra diffuse exosphere because the "atmospheric pressure" is pretty much zero.
...when i hear the word buoyancy, i think water, float, boat, etc. , not the image i am trying to portray.
the math, i stated that .999 = 1, i also said that .333 = 1 and 3.14 =1 and .314 = 1.......wikipedia, .99999999999....read that for a while.....david
As for those other numbers equaling 1? Huh?
cheers
