Corkscrewed down 20 feet underwater to do a barrel roll over a field of boulders I like to explore, then spiraled back topside. Not a long dive (around 30 secs at normal speed), just a fun one with a glimpse of one of Lake Superior’s Atlantean grottos. Pretty sure the bubble that pops out @ 43 secs came out of my right ear as I pinched my nose and equalized the pressure in my skull. Water clarity perfect on this Sunday morning dive in MY church.
