dude said he tried it and it worked!!!...
there was a dude that couldn't sink during his open water training, he thought he needed more lead.. my instructor told him to wipe some toothpaste in his mouth that helps u to sink... he didn't have an issue sinking afterward![]()
my guess is that he exhaled when taking off his mask.
I can remove and replace a large volume mask without sinking and without adding gas to my BC...do the laws of physics not apply to me?
