Rael watched him go, then lowered her eyes to the table to avoid those of her companions. "I'm sorry," she said softly.
"He mentioned that two million people live in Canuche Town," Miceal said.
He took a sip out of his cup and scowled. "Space, woman, why couldn't you at least have waited until we'd finished our jakek?"
"The coffee's no less good," Van Rycke told him, although he glanced nervously below even as he spoke. The motion of the restaurant had already begun to put the Cup behind them. The effect would be strictly illusory in the event that the worst happened while they were up here, of course, but it was a definite psychological comfort to see it go.
He frowned again as an old memory stirred. "I think she's right, Miceal. Way back in my first year at the Pool, we had an old cracked-helmet retired Cargo-Master as an instructor. I recall his mentioning that ammonium nitrate used to be on the hazardous cargo list at one time before it was dropped for never being carried. I believe he also mentioned that it was actually used as an explosive in olden times. — Damn, I should have remembered that as soon—"
"Power down, Van," Jellico said calmly. "Even you're not a computer. — Here comes our host."
Macgregory did not reclaim his chair. "Come on, space hounds. We're about to witness an experiment."
One of the calls the Canuchean industrialist had made was to order a transport for his party, and a large four-wheel passenger vehicle was waiting for them at the entrance of the tower building when they emerged from it a few minutes later.
It made no delay in carrying them through the crowded streets and deposited them in short order before the main entrance of the giant Caledonia, Inc., plant.
Adroo nodded to the guard stationed there and led his guests inside. "Our research quarters are this way."
It was through the clerical portion of the huge facility that he conducted them rather than through those sections where Caledonia's numerous products were made or assembled. Here were no coverall-clad laborers driving their I minitrucks, lifters, or manipulators or commanding their banks of robots but, rather, fashionably dressed men and i women seated at desks or moving in an office worker's universal hurry along the seemingly endless hallways.
Once again, Rael was struck by the suitability of their i' Trade uniforms. They attracted no notice, or none beyond the inevitable interest aroused by the company in which they traveled.
She gave a wry smile. That held true only for their dress uniforms, she amended. They would not make such an appealing picture after a few hours shoving cargo around, particularly on some low-mech steam pit like Queex's Tabor or Amazoon of Indra.
"Here's the Research Center," Macgregory told them at last, echoing the sign on the big double swinging doors as he pushed his way through them.
Another maze of corridors awaited them on the other side, in general appearance much the same as those they had left behind save that the people they encountered now were wearing white. Most also had their hair confined in san-nets and their hands covered by the light, supple laboratory gloves that were standard equipment in such installations throughout the Federation.
A technician whom Rael judged to be about Dane Thor- son's age approached them. "We're all set, Mr. Macgregory."
"Lead the way."
In response, she opened a door on their left, this one a panel that silently slid to a tight close behind them.
They found themselves in a hall or walkway about five feet wide that completely encircled a sealed chamber walled off from them by a barrier of some colorless, transparent material. The ceiling above the enclosed place was a mass of lights and odd instruments as complex in appearance as the bridge of the Solar Queen. The floor was a seamless sheet of dull-finished metal.
The whole place was empty save for a single metal sphere approximately one foot in diameter resting in splendid isolation in what appeared to be its exact center.
"The control panel's over here," the technician told them.
They followed her a quarter around the perimeter of the room until they came to a two-foot-square board of dials and gauges that made a fitting complement to the bewildering ceiling inside.
"That ball is a miniature laboratory," Adroo explained.
"We put the substance to be tested in the bottom half, seal on the top, and introduce whatever forces or elements we want while the sensors fixed on the interior monitor the results. Despite being easily handled, it's a sturdy little device and is equipped with escape valves to release gases before they can build up dangerous pressure levels."
Jellico tapped the crystal wall separating them from the ball. "Shatterproof?"
"Of course. We don't take chances when dealing with potentially hazardous materials. Those balls are strong, but they're not invincible, and neither are my staff members who have to deal with them."
"What now?"
"We're more or less simulating the hold of a freighter.
We packed a proportionally equivalent volume of ammonium nitrate in the lab, and now we're going to subject it to some abuse."
"Electricity first, sir?" the white-garbed woman asked.
"Or a spark?"
"I believe Doctor Cofort mentioned a sudden, sharp rise in temperature. Try direct contact with fire."
"Very good, sir."
She bent over her console. Her fingers deftly touched one button, then moved to a finely calibrated dial. Immediately, a slender wire descended from the ceiling. It hovered over the sphere an instant before finding and entering a small hole at its top. "We'll start out with a relatively cool flame, like that of a normal fire," she said, "and increase the temperature every few milliseconds until there's a reaction ..."
A sudden, searing flash lit the sealed chamber followed
almost in the same instant by a sharp clap of sound clearly audible through the screening walls confining it. Rael stifled a scream as she threw her hands before her face in an instinctive effort to ward off the glowing objects hurtling toward them from the shattered ball.
It was over seemingly in the moment it began. When the observers collected themselves once more, they stared in awe at the place where the miniature laboratory had been.
All that remained of it now was a blackened patch on the floor and some twisted fragments scattered throughout the chamber.
"Lord of Light and Dark," whispered the Canuchean woman. "The valves were operational . . ."
"They just couldn't handle this," Jellico responded briskly. His fingers followed the line of the scratch a piece of shrapnel had gouged in the shielding material in front of him. If the barrier had not held, it would have sliced through his throat. "Your little lab wasn't designed to endure old-fashioned brute force," he told her. "It was meant to conduct sane experiments, not contain a bomb blast."
"A what?" Macgregofy demanded sharply.
Van Rycke shrugged. "What else would you call it? It even fitted the stereotype image—a round, explosive-filled metal ball with a fuse sticking out of it, or sticking into it
in this case."
"It behaved like one at any rate," Adroo agreed. He turned to his employee. "You recorded the whole thing, of course?"
"Naturally." There was no diffidence in that answer.
This was her job; she knew how to do it. "There were some returns from the lab as well. I won't know how much we got until I go over the recordings."
"Get on it, then see if you can replicate the results under a variety of circumstances. Use less expensive bomb cases.
We can recoup our costs later as part of a civic service claim, but we're not likely to collect in a hurry."
She smiled. "Yes, sir."
"And for the Lord of Light's sake, don't get yourself or anyone else killed. That may be a safe room, but it's not going to hold a baby planetbuster."
