Figure 1 shows the top view of a lawn sprinkler. The Swastika-shaped arms rotate freely around a central pivot which supplies water to the arms. Water is sprinkled through the nozzles located at the end of the arms, which causes the sprinkler head to rotate. Now, imagine the whole sprinkler submerged under water and imagine the water being aspirated (suctioned) instead of being expelled. Which direction will the sprinkler head rotate?
