Popis:	A simple method for obtaining the density of liquid under pressure by means of the measurement of the buoyancy of a weight hung on a thin, suspending wire in the sample liquid up to the pressures of 700 MPa at room temperature is presented. The buoyancy was obtained from the tension of the suspending wire through a repeated operation with the pressure vessel in a vertical position and then in a horizontal position. Moving the pressure vessel in a seesaw fashion around the horizontal position was effective in eliminating residual tension due to friction between the weight and the inner wall of the pressure chamber. A method to experimentally estimate the influence of pressure on the proportionality coefficient relating the resistance change of a suspending wire with the tension is presented.
