I want to see how long I can hold my breath underwater using this new dive mask! I have a super deep bath tub to practice in, and my weight belt will hold me underwater. I make several attempts! I'm still not great at holding my breath but each time I go longer, and longer. I love the way the dive mask shows off how desperate to breathe I am, as you can see my eyes. The final breath hold is so intense, I'm completely out of breath as I take the mask off.
