First I have my hand at trying to sit 2 pop a huge Cattex GL700 220cm balloon. This one was extremely hard to pop and made me break out into a sweat trying. Definitely got a work out bouncing up and down completely nude. I then take out a beautiful Cattex 35" Giant Marble balloon. After all the practice on the green balloon I was ready to put some pain on the marble balloon. Watch my butt today pound on both of these balloons.
