1920x1080 HD I blow up 2 balloons and they are both 14 inches. I love blowing up balloons and feeling all my strong lungs fill up the balloons is always so cool. I am pretty petite and but I have a set of strong lungs. I love blowing up balloons and then bouncing on them until they pop. I blow the first one up and then I sit and bounce on it for a long time. I really bounce super hard and it does not pop. I grab another 14 inch balloon and I start to blow it up. I bounce and blow! I then finally pop the balloon I am sitting on. I try and pop the second balloon but I decide to let it not be popped.
