UFO Portal? What is this?

If you played the clip backwards it would look a lot like a volcanic eruption. Not
sure, I am just saying...

Thanks for everyone's input! Internos, I agree with your assessment. . just thought that if ANY website could get to the bottom of it, or at least help with my questions surrounding it, ATS is the place. I emailed the youtube poster of the vid asking some questions and as soon as I hear back, I'll let ya'll know.

I thought this website was not only to inform, but to speculate as to origins of certain things, situations, photos, videos? That is my reasoning for posting it. If you think it's a waste of time, move on. However, I appreciate and respect your comment Internos! No harm done. .
