Sarah is trying to see if she can pop this beach ball with the strength of her legs. She wraps her legs around it and locks her ankles and then squeezes her thighs and calves as hard as she can. She does this over and over. Finally, she gives up, this beach ball is really strong. So, she opens the air tube with her fingers and squeezes all the air out with her legs. Not quite as gratifying as a big pop would have been, but in the end deflated nonetheless from the strength of her legs.
