In Slide Exit, 40.000 slides, that Steven Jouwersma collected in exchange for apple cakes, are destroyed. In front of the Tschumi pavilion there is a post with a red button. If the button is pressed, a slide is being projected. Curiosity of the next slide makes the former one end up in the shredding machine. The 40.000 slides can be seen one last time, before they turn into a heap of grit.
