The last night I was getting a room full of balloons ready for my girlfriend to come home and enjoy with me, started to blow up a Printed Cz&f Big Nose 140 and bang!! I had it kind of blown up the night before, areas were tight and other areas were still stretchy (end of nose, top of head). I start by inflating the nose but just can't get it to stretch enough, I will start inflating the head and nose sucks in. So fooled with it last night and bang!!! Sad thing is got another one and BANG!!!! What a BANG!!!!! Can some one point me in the right direction?
