charge.” The lights in the cabin came on again. Masters flipped the switch beside him, and the paper clip and pencil promptly dropped through the frame into his lap as the bubble burst.
    “I call it electro-reactive collimation, a realignment of the molecular structure of the soap solution so that the surface tension of the solution is millions of times stronger than normal,” Masters said. “Collimation occurs in nature all the time, but it’s usually induced by temperature or chemical interactions. I can make it occur with the application of a small electric current. By varying the amperage and frequency of the electric charge, I can also vary the properties of the collimated material.”
    “How long have you been working on this process, Doctor?” one of the execs asked.
    “Oh, about thirty years,” Masters replied. “I first discovered it when I was around seven years old. I knew lots of kids who played with soap bubbles, but as far as I know I was the only one who shot anelectric current through one. I just hooked up an old six-volt dry cell to the wire frame, and there it was.”
    “This is all very fascinating, Doctor,” Fenton said, “but can we get to the point of this demonstration?”
    “Sure, Ed.” He held up a piece of cloth mounted on a frame with wires attached to it. “It’s possible to collimate a whole variety of liquids and colloids—those are substances that have properties of liquids, solids, or gases combined. I can even use seawater to protect ships and submarines from collision or from damage due to water pressure—imagine a submarine that can dive to the deepest depths of the oceans without being crushed, using the seawater around it, the very thing trying to crush the ship, to
protect
it! Of course, it’s also possible to
de
collimate something, or make it
less
dense, without using temperature or without mixing other chemicals in it. When I get that technology working, the applications will be truly
Star
Wars-like—can you say ‘phaser guns,’ boys and girls?
    “But the really cool application of electro-reactive collimation is in materials science, and it’s there that I’ve had the most fun over the past couple years,” Masters went on, his excitement evident in his voice. “That’s because solids can be collimated just like liquids and gases. Now we start getting into some really neat applications!” He held up another, larger wire frame, this time with a thin, light gray material hung within it. “This is a piece of one of the BERP materials I’ve developed. It’s lightweight fabric, about as light and flexible as nylon.” He rustled the frame, and the fabric swayed as everyone expected. “Now check this out.”
    Masters picked up a hammer, hefted it, and swung it at the fabric. The observers were stunnedto hear a dull thud. They saw Masters drop the wire frame after he hit it with the hammer, but they were still too startled to take any notice. He picked up the frame and shook it again, and the fabric moved as before, like a linen handkerchief—but when he swung the hammer, the fabric again instantly solidified into a hard plate.
    He also dropped it again after he hit it, jumping in surprise when the electric shock came, a bit stronger this time. And this time Helen Kaddiri noticed. “Jon, what’s wrong?” she radioed to him via his earset communications unit. “Why do you keep dropping it?” There was no reply, confirming Helen’s worst fear. “Jon, is that thing shocking you again?”
    “It’s nothing, Helen,” Masters whispered, loud enough for his voice to be picked up on the private earset link but not loud enough to be heard by those watching the demonstration in Washington. “I’ll just hold it with the pliers, like we planned.”
    “But if it’s malfunctioning, you’ve got to terminate the demonstration,” Helen said, horrified. “It’s one thing to shock your hand. But if it lets off a voltage spike next to a hundred pounds of TNT,
