An awesome fan sent me a couple of big mouse balloons! I already inflated one the other day, but having that one around made me really want to see how much bigger it would get. I decided to pull out the other one and get it started on my pump in this video, then lean against the other mouse balloon as I finish it off with my breath. I love not knowing how big a new balloon will get when I blow to pop it for the first time!
