Description	Experimental work dealing with influence of liquid properties on behavior of medium-sized ellipsoidal bubbles (equivalent diameter 4 ? 10 mm) is submitted in the contribution. The ellipsoidal bubble exhibits periodical motion with characteristic nonlinear trajectory. Contexture of the horizontal motion and the bubble wobbling is a course for characteristic bubble orientation throughout rising ? bubble turns to ambient flow with the maximum cross-section. Experimental results obtained in water and glycerol solutions show that bubble inclination and horizontal velocity exhibit the same frequency of oscillation. In-phase oscillation appears in water, phase shift is observed in more viscous liquids. Frequency of the oscillatory motion is f = 5-7 s-1, horizontal velocity 0.15 m.s-1, rising velocity 0.15-0.25 m.s-1, amplitude of horizontal motion is less than 15 mm. In presented work, we focuse on bubble behavior in various liquids. To determine an effect of surface tension, we decided to make experiments Experimental work dealing with influence of liquid properties on behavior of medium-sized ellipsoidal bubbles (equivalent diameter 4 ? 10 mm) is submitted in the contribution.
