I have lots of pretty 12 inch crystal balloons in my room. I'm going to inflate one more though, and blow it up until it pops. A blue crystal 17 inch balloon. Do you want to watch me? I play with the other balloons, and compare the size of the 17 inch balloon to one of the blue 12 inch balloons. Watch the neck grow as I keep blowing up the balloon. It stretches and tightens. I love the wet streaks that fill the inside of the balloon. Can you guess when the balloon will pop?
