I got these two pretty little beachballs that I wanted to try to sit to pop. I pound my butt onto both of them for several minutes before pulling out the assistance of a pin. I poke little holes into each one as I sit on them and they deflate. I take my finger into one and tear one of the holes bigger to get the job done quicker. At the end, I tear each beachball into shreds. I also blow to pop two balloons while sitting on a beach ball, a small metallic pink balloon and a solid pink 16-inch balloon.
