Drea's Blowing Pressure Test (MP4 - 1080p)
Drea continues her routine blowing tests, and this time seeks to determine how much air pressure she can generate. She makes several attempts, both sitting and standing, and with her cheeks held in and "puffed up." She really does not know what pressure she will be able to achieve, but is relived when she exceeds 3 psi, as only about 10% of our test subjects have.
