“Plenty,” Gallegher said. “It has to be. Nonorganic, mineral content of solid earth, compacted and compressed into wire. Sure, it’s got tensile strength. Only you couldn’t support a ton weight with it.”
Wall nodded. “Of course not. It would cut through steel like a thread through butter. Fine, Mr. Gallegher. We’ll have to make tests—”
“Go ahead. It’ll stand up. You can run this wire around comers all you want, from one end of a spaceship to another, and it’ll never snap under stress. It’s too thin. It won’t—it can’t—be strained unevenly, because it’s too thin. A wire cable couldn’t do it. You needed flexibility that wouldn’t cancel tensile strength. The only possible answer was a thin, tough wire.”
The commander grinned. That was enough.
“We*U have the routine tests,” he said. “Need any money now, though? We’ll advance anything you need, within reason—say up to ten thousand.”
Hopper pushed forward. “I never ordered wire, Gallegher. So you haven’t fulfilled my commission.”
Gallegher didn’t answer. He was adjusting his lamp. The wire changed from blue to yellow fluorescence, and then to red.
“This is your screen, wise guy,” Gallegher said. “See the pretty colors?”
“Naturally I see them! I’m not blind. But—”
“Different colors, depending on how many angstroms I use. Thus. Red. Blue. Red again. Yellow. And when I turn off the lamp—”
