FIELD: simulation of processes occurring in the universe. SUBSTANCE: base carrying planet-simulating body having inner cavity to receive dropping liquid is rotated by means of drive. Body is installed on shaft inside container disposed within channel made in base. Channel accommodates two identical springs contiguous with their slider or each of their adjacent end is contiguous with container wall. Compression force of spring is varied by means of adapter that couples external sliders and enables their displacement. Shaft speed is measured and controlled until length of both springs becomes equal to attain critical peripheral velocity of gravity center of body at respective radius of its rotation. Planet-simulating body is set in rotary motion about shaft whereon it is mounted. Its speed of rotation about its axis is controlled, then dropping liquid is supplied to channel made on surface of planet-simulating body from inner cavity of the latter. Body speed of rotation about its axis is gradually increased until liquid escapes from channel to surrounding space. Critical value of peripheral velocity of rotating dropping-liquid particles is computed. Then shaft mounting planet-simulating body installed in container is disconnected from drive with the result that stopping rotation of body causes escape of dropping liquid remained in channel into surrounding space thereby supporting the statement that planet-simulating body has to rotate about its axis in order to hold dropping liquid in channel made on its surface. EFFECT: facilitated procedure. 9 cl, 10 dwg
