Re: Need answer to something I've always Wondered About
As kids snorkelling on the Great Barrier Reef, we sometimes used a large tough clear plastic bag that was held open at the mouth with a wire frame weighted at the corners and sunk a few feet to the bottom, to provide a few lungfuls more air before we needed to head back to the surface.
You might be able to do something like this with a hose and one-way valve fitted to the top of the bag, breathe in through it and exhale through the mouth...but we never got sophisticated enough to try it.. and I imagine you'd need a really large bag to get more than a half dozen breaths out of it.
