Stormgate he/him Posted January 1, 2016 Posted January 1, 2016 Am I the only one who goes outside, feels that it's cold, and immediately exhales to get "dragon breath" fog? 3
Young Bard he/him Posted January 2, 2016 Posted January 2, 2016 Technically, dragon's breath isn't about hot or cold air. It's about the difference in temperature. You get dragon's breath after you move from the warm area of your heated home or wherever indoors you were, to the cold outdoors. Your breath is part of that warm air indoors, which is why after the first few breaths it's not visible anymore. Your breath is now of that cold outdoorsy. It's cold meets cold: nothing happens. That's me saying that it's impossible to be 'too warm' too get dragon's breath.
Stormgate he/him Posted January 2, 2016 Author Posted January 2, 2016 Your body is consistently the same temperature, and will continue to make your breath that temperature unless there is something wrong with you. 2
Oversleep Posted January 2, 2016 Posted January 2, 2016 I do that only to check temperature. Those days when it's cold, but the visible breath means temperature around 0°C.
Ookla the Absent Posted January 8, 2016 Posted January 8, 2016 Not instinctively, no, and if I do it's to see how angry I can expect to be when I get in the car. I hate fog in cars.
The Honor Spren she/her Posted January 9, 2016 Posted January 9, 2016 I'm the only person who checked the third option . . .

That's me saying that it's impossible to be 'too warm' too get dragon's breath. Technically, the way that "dragon's breath" forms is when your moist breath meets the cold air, saturating it to it's dewpoint. You form fog by making the air reach it's dewpoint (Dewpoint is the point at which air at a constant pressure will become 100% saturated with water vapor and it becomes fog). The two ways that you can form fog is by either cooling the air, or adding moisture to the air. You see, cold air is able to hold less water vapor than warm air can because of the difference in pressure. By breathing out in the cold air, you are adding moisture to the air and creating fog. The reason that you can't see your breath inside is because the dewpoint is higher and you need more moisture than what is in your breath to saturate the air. I am trying to become a pilot so I have to know this kind of stuff. We airplane flyers have to know our clouds man. 2
kaellok he/him Posted January 9, 2016 Posted January 9, 2016 (edited) If there's a shiny or reflective surface, I'll try to get it coming out of nostrils + mouth all at the same time. I love it. Best part of the cold, imo, and makes up for a lot. It's like, why are you cold and useless?! If it's gonna be cold anyway, may as well give me a while where I can pretend to be a fierce, fire-breathing lizard that gobbles people whole. Edited January 9, 2016 by kaellok

Dunkum he/him Posted January 19, 2016 Posted January 19, 2016 I don't do it every time, but pretty often, yes. also, sometimes if I am drinking a cold drink, like water with a ton of ice in it, the same effect happens when breathing near/into the glass.
