Student’s laboratory work is a significant pedagogical tool for the physics teaching in natural sciences or engineering. Experiments on fluids physics are often obscure to show the physics of the process and expensive. Masses and forces are accurately measured by electronic balances and can be adapted to the study of fluids; e.g., to measure the densities of solids and liquids measuring the push on a solid and applying the principle of Archimedes or to measure the Stokes’ force on a sphere in a fluid in movement and the viscosity of the fluid, and even to distinguish between Newtonian and non Newtonian fluids. The tear-off force of a metallic ring placed on the surface of a liquid allows us to determine the surface tension. In this paper several inexpensive and simple didactic experiments are proposed to study the ndamental properties of fluids.
