Basically for my story, character A, is pointing a gun at character B. Character B, has an electrical torturing device, he is using to get information out of character C. For the plot to go how I want, I want character B, to overpower character A, but A has a gun pointed at him.
I thought maybe that character B, could perhaps spill a jug of water on the floor, the water would make it's way from character C to character A, as A was pointing the gun B. B can then quickly flip an electrical switch, causing the electricity to pass from the torturing device, through character C, out of character C onto the water on the floor, then through the water, then from the water, to character B, as long as B and C are in contact with the water.
Would that work or be physically possible with electricity? Either way, I want character B to somehow overpower A, who has a gun, if that won't work.
