THE BIG BOUNCE
by
WALTER S. TEVIS
Seeing it in action, anybody would quaver in alarm: What hath Farnsworth overwrought?
Illustrated by Johnson

"Let me show you something," Farnsworth said. He set his near-empty drink--a Bacardi martini--on the mantel and waddled out of the room toward the basement.
I sat in my big leather chair, feeling very peaceful with the world, watching the fire. Whatever Farnsworth would have to show to-night would be far more entertaining than watching T.V.--my custom on other evenings. Farnsworth, with his four labs in the house and his very tricky mind, never failed to provide my best night of the week.
When he returned, after a moment, he had with him a small box, about three inches square. He held this carefully in one hand and stood by the fireplace dramatically--or as dramatically as a very small, very fat man with pink cheeks can stand by a fireplace of the sort that seems to demand a big man with tweeds, pipe and, perhaps, a saber wound.
Anyway, he held the box dramatically and he said, "Last week, I was playing around in the chem lab, trying to make a new kind of rubber eraser. Did quite well with the other drafting equipment, you know, especially the dimensional curve and the photosensitive ink. Well, I approached the job by trying for a material that would absorb graphite without abrading paper."
I was a little disappointed with this; it sounded pretty tame. But I said, "How did it come out?"
* * * * *
He screwed his pudgy face up thoughtfully. "Synthesized the material, all right, and it seems to work, but the interesting thing is that it has a certain--ah--secondary property that would make it quite awkward to use. Interesting property, though. Unique, I am inclined to believe."
This began to sound more like it. "And what property is that?" I poured myself a shot of straight rum from the bottle sitting on the table beside me. I did not like straight rum, but I preferred it to Farnsworth's rather imaginative cocktails.
"I'll show you, John," he said. He opened the box and I could see that it was packed with some kind of batting. He fished in this and withdrew a gray ball about the size of a golfball and set the box on the mantel.
"And that's the--eraser?" I asked.
"Yes," he said. Then he squatted down, held the ball about a half-inch from the floor, dropped it.
It bounced, naturally enough. Then it bounced again. And again. Only this was not natural, for on the second bounce the ball went higher in the air than on the first, and on the third bounce higher still. After a half minute, my eyes were bugging out and the little ball was bouncing four feet in the air and going higher each time.
I grabbed my glass. "What the hell!" I said.
Farnsworth caught the ball in a pudgy hand and held it. He was smiling a little sheepishly. "Interesting effect, isn't it?"
"Now wait a minute," I said, beginning to think about it. "What's the gimmick? What kind of motor do you have in that thing?"
His eyes were wide and a little hurt. "No gimmick, John. None at all. Just a very peculiar molecular structure."
"Structure!" I said. "Bouncing balls just don't pick up energy out of nowhere, I don't care how their molecules are put together. And you don't get energy out without putting energy in."
"Oh," he said, "that's the really interesting thing. Of course you're right; energy does go into the ball. Here, I'll show you."
He let the ball drop again and it began bouncing, higher and higher, until it was hitting the ceiling. Farnsworth reached out to catch it, but he fumbled and the thing glanced off his hand, hit the mantelpiece and zipped across the room. It banged into the far wall, richocheted, banked off three other walls, picking up speed all the time.
When it whizzed by me like a rifle bullet, I began to get worried, but it hit against one of the heavy draperies by the window and this damped its motion enough so
