Some people were commenting about how huge the 11 inch balloons were in my "Helium Birthday Balloons Pop and Play" video, so I wanted to try to blow2pop a couple to see how big they can really get! Let's just say these balloons do not disappoint! I over inflate 2 11 inch crystal balloons (red and purple) by mouth to see how big they can before they pop! I'm amazed by how stretched out the necks get before they pop. These balloons get a lot bigger than 11 inches! Wearing a black bra, matching panties, fishnet shirt, and high heels.
