Funny and overwrought story of what happened when an airline pilot emptied his drinks cooler into the toilet without realizing that it contained dry ice, not water-ice.
And it's now that the noise begins. As he steps away, the pilot hears a deep and powerful burble, which immediately repeats itself and seems to emanate from somewhere in the bowels of the plane. How to describe it? It's similar to the sound your own innards might make if you've eaten an entire pizza or, perhaps, swallowed Drano, amplified a thousand times over. The pilot stops and a quick shot of adrenaline pulses into his veins. What was that? It grows louder. Then there's a rumble, a vibration passes up through his feet, and from behind him comes a loud swishing noise.
He turns and looks at the toilet. But it has, for all practical purposes, disappeared, and where it once rested he now finds what he will later describe only as a vision. In place of the commode roars a fluorescent blue waterfall, a huge, heaving cascade of toilet fluid thrust waist-high into the air and splashing into all four corners of the lavatory. Pouring from the top of this volcano, like smoke out of a factory chimney, is a rapidly spreading pall of what looks like steam. He closes his eyes tight for a second, then reopens them. He does this not for the benefit of unwitnessed theatrics, or even to create an embellishing detail for eventual use in a story. He does so because, for the first time in his life, he truly does not believe what has cast itself before him.
