There was no spark or light, but smoke suddenly sprang up along the length of the rope where it adhered to the fence. Kyle knew that the electrical charge provided by the box disrupted the barrier between two substances in the rope. When they merged, there was acid, and as Kyle watched, it quickly ate through the thin metal of the fence. Both Quess and Douglas, wearing bulky, oversized gloves, held on to the section of the fence so it wouldn't fall. It didn't, and as it bowed and pulled away, they yanked it clear, carefully laying it down on the grass.
