1, A stream of mist is blowing out of the spout.
2, The humidifier blows a stream of mist.
Can I use "blow" in the above two sentences? Does it sound a little weird when I use "blow" to describe an instrument instead of a person?
"Blows" doesn't seem right to me. I'd use either emits or releases. What do you think? If you don't know these words, look them up in the WR dictionary (enter in the box at the top of the page). Does one of them seem right to you?
