Everything is made of atoms.They shook, moved, flowed and flied around. Solid materials' atomic structure was close, a little close. Easy for chakra to connect, move around and bend. Water was a little harder, they had a little more gap between. Ready to part itself. But the pull of material was still strong, it managed to hold a form and made it easier for the user to bend it upon learing how to control. And then there is air. No one was able to control - let alone bending- it. It's structure was the most seperate one, departed from each other.They would touch- and push themselves away again. The air wanted to be free. And no one could tame it. Yet.All Rights Reserved
