Sumario:The main purpose of this article is to present a discrepant experiment, its physical modeling as well as its pedagogical bene ts of the assembly to learn the Bernoulli's Law of hydrodynamic pressure. The impact of the results is presented on a population of students and the interactive engagement is measured starting from a process of dissonance to a process of consonance. The prototype has been implemented as a project in order that the student's population makes time by their own during four weeks. The evolution of the learning process is speci ed with the Hake's average normalized gain and the Bao's concentration factor. The experience has turned out to be quite fruitful from a pedagogical standpoint represented by the Hake's gain values above 0.5.
