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 that it fell to the floor.

       *       *       *       *       *

It started bouncing again immediately, but Farnsworth scrambled across
the room and grabbed it. He was perspiring a little and he began
instantly to transfer the ball from one hand to another and back again
as if it were hot.

"Here," he said, and handed it to me.

I almost dropped it.

"It's like a ball of ice!" I said. "Have you been keeping it in the
refrigerator?"

"No. As a matter of fact, it was at room temperature a few minutes
ago."

"Now wait a minute," I said. "I only teach physics in high school, but
I know better than that. Moving around in warm air doesn't make
anything cold except by evaporation."

"Well, there's your input and output, John," he said. "The ball lost
heat and took on motion. Simple conversion."

My jaw must have dropped to my waist. "Do you mean that that little
thing is converting heat to kinetic energy?"

"Apparently."

"But that's impossible!"

He was beginning to smile thoughtfully. The ball was not as cold now
as it had been and I was holding it in my lap.

"A steam engine does it," he said, "and a steam turbine. Of course,
they're not very efficient."

"They work mechanically, too, and only because water expands when it
turns to steam."

"This seems to do it differently," he said, sipping thoughtfully at
his dark-brown martini. "I don't know exactly how--maybe something
piezo-electric about the way its molecules slide about. I ran some
tests--measured its impact energy in foot pounds and compared that
with the heat loss in BTUs. Seemed to be about 98 per cent efficient,
as close as I could tell. Apparently it converts heat into bounce very
well. Interesting, isn't it?"

"_Interesting?_" I almost came flying out of my chair. My mind was
beginning to spin like crazy. "If you're not pulling my leg with this
thing, Farnsworth, you've got something by the tail there that's just
a little bit bigger than the discovery of fire."

He blushed modestly. "I'd rather thought that myself," he admitted.

"Good Lord, look at the heat that's available!" I said, getting really
excited now.

       *       *       *       *       *

Farnsworth was still smiling, very pleased with himself. "I suppose
you could put this thing in a box, with convection fins, and let it
bounce around inside--"

"I'm way ahead of you," I said. "But that wouldn't work. All your
kinetic energy would go right back to heat, on impact--and eventually
that little ball would build up enough speed to blast its way through
any box you could build."

"Then how would you work it?"

"Well," I said, choking down the rest of my rum, "you'd seal the ball
in a big steel cylinder, attach the cylinder to a crankshaft and
flywheel, give the thing a shake to start the ball bouncing back and
forth, and let it run like a gasoline engine or something. It would
get all the heat it needed from the air in a normal room. Mount the
apparatus in your house and it would pump your water, operate a
generator and keep you cool at the same time!"

I sat down again, shakily, and began pouring myself another drink.

Farnsworth had taken the ball from me and was carefully putting it
back in its padded box. He was visibly showing excitement, too; I
could see that his cheeks were ruddier and his eyes even brighter than
normal. "But what if you want the cooling and don't have any work to
be done?"

"Simple," I said. "You just let the machine turn a flywheel or lift
weights and drop them, or something like that, outside your house. You
have an air intake inside. And if, in the winter, you don't want to
lose heat, you just mount the thing in an outside building, attach it
to your generator and use the power to do whatever you want--heat your
house, say. There's plenty of heat in the outside air even in
December."

"John," said Farnsworth, "you are very ingenious. It might work."

"Of course it'll work." Pictures were beginning to light up in my
head. "And don't you realize that this is the answer to the solar
power problem? Why, mirrors and selenium are, at best, ten per cent
efficient! Think of big pumping stations on the Sahara! All that heat,
all that need for power, for irrigation!" I paused a moment for
effect. "Farnsworth, this can change the very shape of the Earth!"

Farnsworth seemed to be lost in thought. Finally he looked at me
strangely and said, "Perhaps we had better try to build a model."

       *       *       *       *       *

I was so excited by the thing that I couldn't sleep that night. I kept
dreaming of power stations, ocean liners, even automobiles, being
operated by balls bouncing back and forth in cylinders.

I even worked out a spaceship in my mind, a bullet-shaped affair with
a huge rubber ball on its end, gyroscopes to keep it oriented
properly, the ball serving as solution to that biggest of
missile-engineering problems, excess heat. You'd build a huge concrete
launching field, supported all the way down to bedrock, hop in the
ship and start bouncing. Of course it would be kind of a rough
ride....

In the morning, I called my superintendent and told him to get a
substitute for the rest of the week; I was going to be busy.

Then I started working in the machine shop in Farnsworth's basement,
trying to turn out a working model of a device that, by means of a
crankshaft, oleo dampers and a reciprocating cylinder, would pick up
some of that random kinetic energy from the bouncing ball and do
something useful with it, like turning a drive shaft. I was just
working out a convection-and-air pump system for circulating hot air
around the ball when Farnsworth came in.

He had tucked carefully under his arm a sphere of about the size of a
basketball and, if he had made it to my specifications, weighing
thirty-five pounds. He had a worried frown on his forehead.

"It looks good," I said. "What's the trouble?"

"There seems to be a slight hitch," he said. "I've been testing for
conductivity. It seems to be quite low."

"That's what I'm working on now. It's just a mechanical problem of
pumping enough warm air back to the ball. We can do it with no more
than a twenty per cent efficiency loss. In an engine, that's nothing."

"Maybe you're right. But this material conducts heat even less than
rubber does."

"The little ball yesterday didn't seem to have any trouble," I said.

"Naturally not. It had had plenty of time to warm up before I started
it. And its mass-surface area relationship was pretty low--the larger
you make a sphere, of course, the more mass inside in proportion to
the outside area."

"You're right, but I think we can whip it. We may have to honeycomb
the ball and have part of the work the machine does operate a big hot
air pump; but we can work it out."

       *       *       *       *       *

All that day, I worked with lathe, milling machine and hacksaw. After
clamping the new big ball securely to a workbench, Farnsworth pitched
in to help me. But we weren't able to finish by nightfall and
Farnsworth turned his spare bedroom over to me for the night. I was
too tired to go home.

And too tired to sleep soundly, too. Farnsworth lived on the edge of
San Francisco, by a big truck by-pass, and almost all night I wrestled
with the pillow and sheets, listening half-consciously to those heavy
trucks rumbling by, and in my mind, always, that little gray ball,
bouncing and bouncing and bouncing....

At daybreak, I came abruptly fully awake with the sound of crashing
echoing in my ears, a battering sound that seemed to come from the
basement. I grabbed my coat and pants, rushed out of the room, almost
knocked over Farnsworth, who was struggling to get his shoes on out in
the hall, and we scrambled down the two flights of stairs together.

The place was a chaos, battered and bashed equipment everywhere, and
on the floor, overturned against the far wall, the table that the ball
had been clamped to. The ball itself was gone.

I had not been fully asleep all night, and the sight of that mess, and
what it meant, jolted me immediately awake. Something, probably a
heavy truck, had started a tiny oscillation in that ball. And the ball
had been heavy enough to start the table bouncing with it until, by
dancing that table around the room, it had literally torn the clamp
off and shaken itself free. What had happened afterward was obvious,
with the ball building up velocity with every successive bounce.

But where was the ball now?

Suddenly Farnsworth cried out hoarsely, "Look!" and I followed his
outstretched, pudgy finger to where, at one side of the basement, a
window had been broken open--a small window, but plenty big enough for
something the size of a basketball to crash through it.

There was a little weak light coming from outdoors. And then I saw the
ball. It was in Farnsworth's back yard, bouncing a little sluggishly
on the grass. The grass would damp it, hold it back, until we could
get to it. Unless....

I took off up the basement steps like a streak. Just beyond the back
yard, I had caught a glimpse of something that frightened me. A few
yards from where I had seen the ball was the edge of the big six-lane
highway, a broad ribbon of smooth, hard concrete.

[Illustration]

I got through the house to the back porch, rushed out and was in the
back yard just in time to see the ball take its first bounce onto
the concrete. I watched it, fascinated, when it hit--after the soft,
energy absorbing turf, the concrete was like a springboard.
Immediately the ball flew high in the air. I was running across the
yard toward it, praying under my breath, _Fall on that grass next
time_.

It hit before I got to it, and right on the concrete again, and this
time I saw it go straight up at least fifty feet.

       *       *       *       *       *

My mind was suddenly full of thoughts of dragging mattresses from the
house, or making a net or something to stop that hurtling thirty-five
pounds; but I stood where I was, unable to move, and saw it come down
again on the highway. It went up a hundred feet. And down again on the
concrete, about fifteen feet further down the road. In the direction
of the city.

That time it was two hundred feet, and when it hit again, it made a
thud that you could have heard for a quarter of a mile. I could
practically see it flatten out on the road before it took off upward
again, at twice the speed it had hit at.

Suddenly generating an idea, I whirled and ran back to Farnsworth's
house. He was standing in the yard now, shivering from the morning
air, looking at me like a little lost and badly scared child.

"Where are your car keys?" I almost shouted at him.

"In my pocket."

"Come on!"

I took him by the arm and half dragged him to the carport. I got the
keys from him, started the car, and by mangling about seven traffic
laws and three prize rosebushes, managed to get on the highway, facing
in the direction that the ball was heading.

"Look," I said, trying to drive down the road and search for the ball
at the same time. "It's risky, but if I can get the car under it and
we can hop out in time, it should crash through the roof. That ought
to slow it down enough for us to nab it."

"But--what about my car?" Farnsworth bleated.

"What about that first building--or first person--it hits in San
Francisco?"

"Oh," he said. "Hadn't thought of that."

I slowed the car and stuck my head out the window. It was lighter now,
but no sign of the ball. "If it happens to get to town--any town, for
that matter--it'll be falling from about ten or twenty miles. Or
forty."

"Maybe it'll go high enough first so that it'll burn. Like a meteor."

"No chance," I said. "Built-in cooling system, remember?"

Farnsworth formed his mouth into an "Oh" and exactly at that moment
there was a resounding _thump_ and I saw the ball hit in a field,
maybe twenty yards from the edge of the road, and take off again. This
time it didn't seem to double its velocity, and I figured the ground
was soft enough to hold it back--but it wasn't slowing down either,
not with a bounce factor of better than two to one.

       *       *       *       *       *

Without watching for it to go up, I drove as quickly as I could off
the road and over--carrying part of a wire fence with me--to where it
had hit. There was no mistaking it; there was a depression about three
feet deep, like a small crater.

I jumped out of the car and stared up. It took me a few seconds to
spot it, over my head. One side caught by the pale and slanting
morning sunlight, it was only a bright diminishing speck.

The car motor was running and I waited until the ball disappeared for
a moment and then reappeared. I watched for another couple of seconds
until I felt I could make a decent guess on its direction, hollered at
Farnsworth to get out of the car--it had just occurred to me that
there was no use risking his life, too--dove in and drove a hundred
yards or so to the spot I had anticipated.

I stuck my head out the window and up. The ball was the size of an egg
now. I adjusted the car's position, jumped out and ran for my life.

It hit instantly after--about sixty feet from the car. And at the same
time, it occurred to me that what I was trying to do was completely
impossible. Better to hope that the ball hit a pond, or bounced out to
sea, or landed in a sand dune. All we could do would be to follow, and
if it ever was damped down enough, grab it.

It had hit soft ground and didn't double its height that time, but it
had still gone higher. It was out of sight for almost a lifelong
minute.

And then--incredibly rotten luck--it came down, with an ear-shattering
thwack, on the concrete highway again. I had seen it hit, and
instantly afterward I saw a crack as wide as a finger open along the
entire width of the road. And the ball had flown back up like a
rocket.

_My God_, I was thinking, _now it means business. And on the next
bounce...._

It seemed like an incredibly long time that we craned our necks,
Farnsworth and I, watching for it to reappear in the sky. And when it
finally did, we could hardly follow it. It whistled like a bomb and we
saw the gray streak come plummeting to Earth almost a quarter of a
mile away from where we were standing.

But we didn't see it go back up again.

For a moment, we stared at each other silently. Then Farnsworth almost
whispered, "Perhaps it's landed in a pond."

"Or in the world's biggest cow-pile," I said. "Come on!"

We could have met our deaths by rock salt and buckshot that night, if
the farmer who owned that field had been home. We tore up everything
we came to getting across it--including cabbages and rhubarb. But we
had to search for ten minutes, and even then we didn't find the ball.

What we found was a hole in the ground that could have been a
small-scale meteor crater. It was a good twenty feet deep. But at the
bottom, no ball.

       *       *       *       *       *

I stared wildly at it for a full minute before I focused my eyes
enough to see, at the bottom, a thousand little gray fragments.

And immediately it came to both of us at the same time. A poor
conductor, the ball had used up all its available heat on that final
impact. Like a golfball that has been dipped in liquid air and
dropped, it had smashed into thin splinters.

The hole had sloping sides and I scrambled down in it and picked up
one of the pieces, using my handkerchief, folded--there was no telling
just how cold it would be.

It was the stuff, all right. And colder than an icicle.

I climbed out. "Let's go home," I said.

Farnsworth looked at me thoughtfully. Then he sort of cocked his head
to one side and asked, "What do you suppose will happen when those
pieces thaw?"

I stared at him. I began to think of a thousand tiny slivers whizzing
around erratically, richocheting off buildings, in downtown San
Francisco and in twenty counties, and no matter what they hit, moving
and accelerating as long as there was any heat in the air to give them
energy.

And then I saw a tool shed, on the other side of the pasture from us.

But Farnsworth was ahead of me, waddling along, puffing. He got the
shovels out and handed one to me.

We didn't say a word, neither of us, for hours. It takes a long time
to fill a hole twenty feet deep--especially when you're shoveling
very, very carefully and packing down the dirt very, very hard.
