On a dive at Columbia Shallows, was hitting the hour mark, getting a little bored... see above us a group of teenage girl snorkelers, sneak up under them about 15 feet below, take both regs and dump a ton of air while spinning around. The effect is the girls are suddenly engulfed in a cauldron of boiling bubbling water for about 10 seconds. The looks on their faces were priceless, they went from shock and surprise to giggles and laughter as they figured it out, then they kept following me from above, I guess hoping for another round.
