In our laboratory, manufacture and launch experiment of PET bottle rocket have been carried out for the students of 2nd grade as engineering introductive education of fluid dynamics. The visualization experiment of separation vortex using hydrogen bubble method over the PET bottle rocket, was performed in order to understand a stall phenomenon arising in the rocket at the optimum launching angle, which is calculated theoretically. In this paper, the actual circumstances of the combined experiments over the two grades, and the educational effects have been presented.
