Several different flow visualization techniques are used to observe, both in air and in water, the features of well ordered streamwise vortices downstream of a slender axisymmetric cylinder with a slanted base. The visualization techniques used include surface skin friction visualization, helium bubble technique, and total pressure field representation (in air) and a tracer technique (in water). Results of the flow visualization of the body wake are presented along with examples of balance measurements and pressure measurements on the bas
