In the center of the frame is a clear plastic 18-inch by eight-inch pill shaped tank that is partially filled with green colored water. A pair of high resolution cameras will record the movement of the liquid inside the tank as the experiment is pushed around by the SPHERES robots. Additionally, several inertial measurement units will accurately record the position of the experiment as it moves within the space station.
