I've got a couple of 36" Cattex longneck balloons and I'm having a bit of trouble with getting the neck to come out on one.
I made sure to prestretch the neck well by holding the bulb and inflating the neck several times. I also stretch the neck while inflating and have even clipped the balloon shut and rode it a bit while it was underinflated to keep stretching the neck. Whenever it gets to its rated size, though, the neck only bulges out slightly and there doesn't seem to be enough pressure in the bulb to get the neck to come out. I don't continue inflating past its rated size because I really don't want to pop it but I also want the neck. Will the bulb ever build up enough pressure to get the neck to come out with further inflation or is there some sort of trick that I'm not realizing to this? I really don't want to end up accidentally popping it from weakening the neck so much from further pre-stretching that it's reached all it can handle.
