I'm getting ready to film a balloon popping video, but in order to pop the balloon, I have to fill it first. And this isn't just any old balloon. No, this is a 36" clear giant. Much too big to fill with my lungs, so it's a good thing I have this pump. I use the hand pump to air into the balloon, and watch it get bigger, and bigger. It gets so huge! My arms get tired of the constant strokes, so I pause to take a break and get some photos of myself with the balloon, before continuing to inflate this monster.
