practicing a new technique

Darthwin was floating in the air above a large body of water, as he began to form a energy ball in his hand. The ball of energy began to expand slowly until it was about the size of a basket ball now. "ok time to unleash this move Giga ball" he thought, as he threw it towards the water and began to control it's movements with the hand he had thrown it with the hand that he had thrown the ki ball with. He maneuvered it around keeping each movement of the attack unpredictable until he sent into the water causing a small explosion once it hit the water.
