A rotation container converts potential energy into kinetic energy to rotate as water rotates a water wheel. The container comprises a dual container in a spiral shape and a rotation contact surface disposed on a bottom surface of the container. When the container rotates, a weight balance is maintained. The container is tilted when empty. When the container is filled with a filling material, the container rotates and stands upright. When the container is completely filled with the filling material, the container rotates in a reverse direction and spills the filling material to return to an original container condition. The container comprises the dual container having an inner and an outer container mounted on each other, and the rotation contact surface having a slope disposed on the bottom surface of the container. The filling material and a thickness and a weight of a container material are selected and distributed to maintain a balance when the container rotates. The rotation container gives a lesson of ″Be cautious about fully filling.″ A user slowly drinks the filling material in a spiral space (P) and estimates an amount of the filling material according to a slope. The container is more thermally insulative. |
