The Smart Fun Side of Water
Hydrodynamics or the study of fluids in motion and the forces immersed on solid bodies immersed in fluids and the relative motion, has a varied range of applications ranging from water conservancy, hydro power, coastal engineering, energy exploration, weather predictions, wave dynamics, river hydrology, pipeline flows and the list continues into a sublist of sublists of critical fields of study and practical applications. In the end, it's a whole lot of fun to throw multicolored plastic balls into a water vortex and watch 'em swirl.
