I have a beautiful blue balloon that I have decorated that I want to blow up really big. I blow some breaths into the balloon and I squeak it with my fingers. I decide to make you help me blow up my pretty balloon so I hold the balloon for you so you can blow a few breaths into it. We alternate blowing up my balloon a few times and we watch as it gets really BIG. My balloon finally gets so big it can't hold any more air and finally POPS!
