Some authors showed that the results obtained for the movement of particle fall in liquids could not be extended to describe the rising of light particles with the same diameter in the same difference of density conditions, especially in the region of higher Reynolds number. The main objective of this study was the investigation of the dynamic behavior of light spheres and of gas bubbles isolated in stagnant liquids. The experimental data of the rising of light spheres and bubbles were obtained with photographic techniques and a stroboscope. The obtained results showed that there were significant differences between the behavior of the ascending gas bubbles and the solid particles in free fall.
