To demonstrate for your OW/CMAS1* students that you should always keep your airways open and never close your glottis.The question is: why blow bubbles when you're neutral? What's the point?
While we - who of course are world class divers and always follow perfect practice (</sarcasm>) - are able to keep our airways open while not blowing bubbles, OW students can't be trusted to do that. So they're taught to blow a tiny stream of bubbles when they take their reg out of their gob.
