In this clip, I grind on a standard beach ball, until I decide to pop it using a pen. I rode the ball down to about 3/4 empty then I squish the rest of the air out with my hands. Then I am sitting on top of a special beach ball, the lavender 99 Cent Store Beach ball, which has plasticizer inside it to soften it- this also ended up stretching and enlarging the ball. I sat on the beach ball and I am shocked and surprised when it pops. I didn’t realize it would pop so easily. I wasn’t planning to pop this ball so I am sad that it popped. (luckily I have another one somewhere)
