How to blow up a ballon without using your mouth

I've been waiting for this since Harrison started preschool. I've collected different Science Fair projects for him to complete throughout his elementary/middle/high school experience. Needless to say, I was a bit excited, but that excitement was short-lived. Keeping with the new trend that every child is a winner, the projects were not judged. I remember growing up that this was the most exciting part, did you get to carry home the coveted blue ribbon? It pushed you do better next year, but noooo all kids are winners. Baloney! How do they expect these children to function as productive adults in the real world? Enough venting, here are the pix.
