Yep, it could have been Rainier letting a fart. I use to amuse the intro divers when I worked as a divemaster in Maui by taking my regulator out of my mouth underwater and blowing water rings up to the surface. Intro divers are easily amused because they're so over-stimulated by their first time...underwater, that is.
