Glass, Rubber, and Fabric. Those are the options you're given.
You run over them in your head, and come up with nothing. As with all of the choices, what will happen is entirely obscured behind obfuscated terms. As the timer runs down, you pick Glass and watch the screen.
The gloved hands reach in and grab your crying cousin, along with the source of her pain. Then, the screen switches to another view.
Jane is still suspended on the pencil, this time the background is a white wall. The hands swoop in with a pair of tweezers, and a long, thin tube. They forcefully expand Jane's vagina with the tweezers, then slip in the tube alongside the pencil. A clear liquid flows along the tube into Jane. Then the tube is drained of liquid, and the hands flick your cousin's breasts before leaving.
You watch for another half hour as Jane continues to sob and shriek, then the hands return. They grab the pencil and turn it upside down, but Jane stays. The realization dawns on you that they glued Jane to the pencil.
Next the hands appear with a variety of clear tubes and begin to insert them, one in her rear, and one to her mouth, in addition to the one in her vagina.
Next, the hands appear with a brush. They thoroughly coat every part of Jane, leaving her glistening. Then, she's lifted up and disappears. The camera changes to another shot, this time of a bucket of glowing orange material. The hands bring Jane on camera, then twirl her around for a second, before languorously dipping her into the material. You gasp as she is held under the material as the heat wavers over it for several minutes before the hands remove her.
As they spin her slowly on the screen, you see that she is still moving, but her movements look labored and slow. As the material hardens, her movements eventually become nonexistent, unable to fight against the material. The hands then return with a stick, and begin thinning the material around her, taking it from a thick coating to a thin shell. The eraser of the pencil is then placed into a pedestal of the same material.
You watch on screen for over an hour, and it eventually becomes apparent what has happened. As the material cools down, it becomes clear, with the exception of the sharp black color of the material around the pencil, and you eventually realize it's glass. The tubes embedded in her are invisible, the one leading to her mouth leaving a small hole in the glass, and the ones exiting from her other orifices leading through the pedestal, down off the screen. Jane has been suspended as a living statue, face contorted through pain, cursed to live, but never move.
The screen goes black.
A minute later, the panel slides open and Jane is slid through before it closes again.
