Put one finger out, like you are pointing at someone. Move ki to your finger. Now visualize electricity crackling around your finger. Hear it going snap. After two weeks practice you might start to feel the electricity jumping from place to place, and if you get good enough, you will be able to shock people, literally.
Alright, this takes a couple of weeks to learn. To learn electrokinesis, start out but just closing your eyes, and visualizing electricity flowing inside and out of your body, like sparks of energy. See them shocking, actually hear them crackling and popping. Do this for like 15 minutes a day. If you can project it out of your hands, you can try to shoot it at your TV or radio, and see if it makes the reception a little messed up, or you could try to shock someone.
Close your eyes and visualize the electricity running through the body to your hands. Visualize it running up say, your hand, in waves of electricity. Then after that, visualize it sparking and even arcing out of your finger tips and hands. Try to feel the sparks the best you can, sometimes your fingers will just go sort of numb and they will feel weird if you try to move them. Then open your eyes and do the same thing for a while. Eventually you should start seeing very faint pencil thin lines of electricity or round dot size sparks or both.
This is basically a psi ball with electricity from electrokinesis added into it. To start, visualize the electricity flowing through your body. Then, make a normal psi ball, then picture the electricity bolts coming out of your hands and your fingertips, and merging with the psi ball, making little sparks and shocks around and inside the psi ball. Do this for about 5 minutes a day, along with just picturing the electricity flowing inside of you. Just keep practicing, and when you get the electro-ball, you will be able to shock people with it.
