The major component is a metal plate A and B are parallel, and the d-pad A periodic intervals is a tiny hole drilled over oil, which is A muzzle as a sprayer hole. When the small oil droplets of spray paint in between the metal plates in parallel and then shine a ray will make a difference, the air is electric charge to the island on the oil droplets and then adjust the electrical voltage drops oil with electric charge, which will move up and down with speed in electric power pole, but once here, plus A metal plate and connect the electrode to metal plates, some oil drops, you'll B drops are moving slowly. Some drops of moving faster.
