Showing 3 types of free buzzing. The + and - sides of free buzzing, along with a little general info on how the air evacuates and we respond. A very real warning about the negative side of free buzzing. At one point I mention my "open aperture" this is wrong - I meant to say closed aperture Free Buzzing means without the mouthpiece.
