Carissa puts herself through an extended period of holding it while dying to pee, completely naked throughout. The fact that she is wearing no clothes, not even panties, has a profound psychological effect on her, making holding a bladder full of pee extremely difficult. Carissa's pained expressions and frantic hand movements say much about the desperate state she is in. She has to concentrate extremely hard to last more than half an hour; several times it looked as if she would not make it. For those who enjoy watching a woman pee into a container, Carissa empties her bladder into one of those graduated glass cylinders and checks how much she had been holding. (During filming, Carissa talks about her desperation initially, but as her desperation worsens she falls quiet, and at one point even turns to the cameraman to whimper the word "please", perhaps hoping for his permission to relieve herself, but he does not respond and she carries on holding it).
