*not really sure but as instructed i concentrate my energy in my hands and once they are touching the water, i expel the energy out of my hands and through the puddle. just to make sure i repeat the move and once i am sure of the feeling i move on to the rock. knowing that the rock does not conduct electricity and what i am attempting to do is to shatter it, i gather as much raiton in my hands as i can, then in one violent movement i slam my palms into the rock and once i feel the stone against them i explode the energy out of my hands harming the form of the rock, the damage is yours to asses*
