Hank Green of SciShow excitedly defined why smoke blows on your face and follows you round a hearth no matter wherein you’re sitting.
You realize the way you somehow end up getting smoke on your eyes anyplace you stand around a bonfire? Well, it seems that’s not a curse! It’s lots more easily defined with physics.
As it seems, the human frame blocks the airflow that lets in smoke to get away. If that body become not there, the smoke could truly expend.
…the actual key to knowledge why smoke maintains blowing in your face is that the rising air doesn’t just rise on its own. It is driven by the air around it. Because while hot air moves away from the fire, the air that pushed it keeps right on going and fills the gap that the new air left behind. And this is where you come in.
