Smoke temperatures...

[Randall Flagg 1]

I smoked a hookah with a mate yesterday and I noticed how when he exhaled out the smoke sank but when I exhaled out it went straight up. Could your internal heat be a factor in the smoke? What else could it be?

interesting thought. could be anything from air drafts, to how you hold your mouth when you exhale, to how long you hold in the smoke, to how much air you let in from around where your mouth meets the hose. my guess is there's some sort of draft, maybe a fan, a central air duct, etc. that caused it.

anyone have any thoughts on this phenomenon?

Hmm interesting. What about the way you inhale the smoke? For example, I take long slow hits. My friend takes short large hits. Could be that a faster hit makes the coals heat up faster, making the smoke warmer. Since the smoke is trying to get to you faster it doesn't have time to cool.
