Mike fired up the box and the lasers came to life. The machine produced a small circular area of distortion. It was a vortex about eight inches across that looked like ripples above a fire. This was unexpected. Mike didn’t know what the vortex was or if it was dangerous. So he grabbed a sheet metal screw and tossed it through the field. It vanished. Mike just stared and blinked and waited. The screw was just… gone.
