Sounds like you still don't:
I was just making a sly jab at the fact that we get so much of our information now from a medium which can be so easily faked. In this particular case I believe it because I've seen bubble rings before. But there's gonna come a time when video evidence will be virtually useless.
The Dolphins are amazing. I didn't know they could produce bubble rings, and I didn't know anyone (or anything) could "snap" them apart into smaller rings without disrupting them. The Dolphins are clearly skilled at manipulating fluid currents.
