telophase: (Near - que?)
So I've got that little travel humidifier running in my office. I also have a fan on, because the water vapor mostly falls down to the ground and makes me feel like it's just getting the carpet wet (it vanishes into the air a foot away from the humidifier; it's probably fine), but with teh fan on I get a vague sense that it's blowing into the air. :D

Something I noticed though - the fan is turned away from me because my hair blowing around annoys the fool out of me. The humidifier is offset from it, not in the direct airstream but next to it, and the water vapor coming from the thing gets pulled sideways and back before getting into the airstream. Huh.

Can anyone tell me the physics of this? I assume there's an area of low pressure alongside the stream of air from the fan, which pulls the water vapor in?
