With another click, a second switch was flipped, this time followed by a whining buzz. The blue sparks twisted and grew, spindles of shimmering ionised particles. “Now, with the ionisation at maximal potential, we can assume that all zeta particles have been energised.” Anton paused, his grey eyes set on the hand that had risen. He nodded curtly “Miss Karensa, I believe.”
She nodded, tapping a plastic stylus against her teeth “Professor, I fail to see what the benefits are of this test. What does it achieve?” Anton stepped away from the control panel, indicating the view-screen with a flourish. The blue sparks had dissipated, replaced by a cool pulsing light that filled the room.
