The Exercise Ball Fail So I purchased what I thought was a really cool inflatable exercise ball. The kind you sit upon. The ideas for this thing were endless. Obviously I was recording the unboxing and was set to show off during the inflation process. Surprised by what I found in the box there wasn't any big bouncy ball in this box. As a backup though I had a big pink balloon set to the side. Figuring I would Blow to pop the huge rubber once I was done inflating the ball. Change of plans and the big pink balloon steals the show. I never knew those balloons were so durable.
