*** 720P HD VIDEO WITH STEREO SOUND *** Millie simply inserts a tube into each Mylar Balloon and blows each one up tightly by mouth. This contains the full inflations but the opening of packets etc has been edited out so to keep the action flowing and to keep the price low. You'll hear Millies breaths and hear the balloons creek as they are topped up tightly with warm air from Millies mouth. The balloons themselves are 3 standard sized foil balloons.
