I sit to pop 12-inch crystal pastel Sempertex with a glittery booty in an inflatable pool! The pool makes the balloons even harder to pop as it is inflated at the bottom and cushions them. I have to bounce really hard to pop most of these, though I can't help but grind against them a lot too. I bounce and grind on a 24-inch Silver Sempertex at the end, but decide to save it after having a rough time trying to pop it.
