On an other Stack Exchange forum, I asked a question and I wrote this sentence :
I started to worry when I realized that it had been minutes and minutes (I would say at least 10) since the bubbles were getting out of it at a pretty high outflow (bubbles were constantly getting out).
Is it right ? I am specifically wondering it about the end of the sentence that I putted in bold (can we say "at a pretty high outflow" ?). By the way, does the word "outflow" fits well to the context here ?
