The Podmaster took a small case out of his shirt. He opened it, and held something that glittered in the lowering sun. It was a small square, a tile. There were flecks of light that might have been cheap mica, except that the colors swept in coordinated iridescence. "This is one of the cladding tiles from the satellite. There was also a layer of low-power LEDs, but we've stripped those off. Chemically, what is left is diamond fragments bound in epoxy. Watch." He set the square down on the table and shined a hand light on it. And they all watched....And after a moment the little square of iridescence floated upward. At first, the motion looked like a commonplace of the microgravity environment, a loose paperweight wafting on an air current. But the air in the room was still. And as the seconds passed, the tile moved faster, tumbling, falling...straight up. It hit the ceiling with an audible clink-and remained there.
No one said anything for several seconds.
