It is like jumping into a cement mixer. The blackness envelops me, the momentum pulling my body down the slide as though it were vacuum-pressured. There is a brief sensation of being upended by the circle, my back sliding along the foam surface before it levels out, and I’m returned to an upright position. There is no sense of up or down, only the g-forces tugging at my limbs the way one would torture a Stretch Armstrong doll.
