Josie has been tasked with testing two different compact mouthpieces for blowing 260's and similar small entertainer balloons.  the red one has been in use for a while at the lab, and includes a tiny check valve, which contains a spring that gives it a "cracking pressure" of about 1 psi.  while we do not believe this adds to the pressure required to inflate the balloon, the cross-sectional area of the opening and tube does seem to restrict airflow for fast blowers.  so we built another one with no check valve and a slightly larger tube, which means that the user must manage the back pressure in the event they have to take a breath.  which will she prefer? ]]> Wed 07 Aug 2024 00:13:24 +0200 https://pornfaze.com/videos/6592897/josie-compares-mouthpieces-for-blowing-entertainer-balloons-mp4-720p/ https://pornfaze.com/videos/6592895/josie-compares-mouthpieces-for-blowing-entertainer-balloons-mp4-1080p/
