It's been a while since I have done this, and it always scares me a bit. I'm going to use my electric inflator to inflate to pop (blow to pop) several balloons. It's scary because I never know when they might pop. I inflate several 17 inch balloons and a couple 11 inch balloons. They all over stretch into huge balloons with long necks before they pop! One even stretches so much that it seems like the inflator will never pop it, so I decide to try blowing to pop it by mouth. Are you ready to have some fun with me? Balloons include: Red Tuftex 17", Clear Tuftex 17", Happy Birthday Yellow Qualatex 11", Blue Tuftex 17", Pink Tuftex 11"
