David, thanks for the insight. I guess I didn't think about that long enough. Your explanation makes sense. I was thinking of old mine safety lamps which measure methane by calibrating and then observing flame height. A bigger flame is interpreted as more methane, not less oxygen with safety lamps.

I'm curious as to where I made that statement "shot a fireball",that you refer to.

I HAVE shot quite a few "fireballs" in my time,but not in a cave.. :lol:

It was cvr602 that said:

The lighter struck all the way to the bottom, but at the botom, it just shot a fireball. That is somethnig that low O2 would do

Very large flicker of the flame, without staying lit, is what i meant by fireball, sorry. :)

:lol:
