    Trapped Air Under the Deck?

    A while back I had mentioned a product that destroys surface tension of water and in doing so eliminates those clinging bubbles. Originally the I suggested this after hearing about Cohutta's seltzer pond water . I believe that I received some chuckles and ribbing as a result. I had some time to play this morning and set up a mini test tank, used an old comb (lord knows that I have no further use for a comb) to simulate close deck planks, and made a short video. I know that the effect will last the entire day at the pond with only a single spritz.. after that I can't say. but the video says a thousand words.-BG

    I suggest watching on YouTube (click "watch on YouTube" in the lower right corner of the video window) it will have better resolution...

      Damned good work, Bob. Just ordered a bottle of this stuff -- a must have for underwater camera lens windows.

          David , I know you got this right but for the others watching and reading keep in mind that that company "Method" makes many different products and they're all in almost exactly the same bottles... This one is their shower spray. I never thought of the lens on the camera... perfect! I run into a problem with water drops remaining on the lens when I transition from underwater to above... Then it's flare and artifact City... my old man eyes don't see it until it's on my computer screen at home.. I'm going to have to look for a tiny refillable spray bottle that's airline size for those Caribbean vacations.

              We had a good discussion about this and it's use on my Marlin at Groton. Got your email about it Bob, thanks. The slotted deck on my Marlin does not allow the air under it to pass through the slots. My idea was to carefully remove portions of the deck and modify it so it was hinged so the trapped air would lift the decking and slip out, akin to a hatch. Before I commit to major surgery I will of course try this first.

                  Coat the underside with Pam (spray applied cooking oil) was the old-school method of breaking water-tension.
