Abstract
We propose a semiquantitative experiment that associates video-analysis and ordinary procedures of experimental physics whose objective is to investigate the dual character of Oobleck, a mixture of cornstarch in water, which appears thicker or thinner depending on how it is physically manipulated. The results are presented and interpreted taking into account a macroscopic model present in the literature. The experiment is easily replicable in the most diverse school realities and it may be useful do discuss many fundamental physics concepts.
