A number of papers stated that during charge explosion in fluid a vapourgas bubble formed at explosion point may attract to bottom. The paper considers investigation by numerical calculation of the physics of the phenomenon. The numerical test was performed with a program for solving twodimensional gas dynamics problems on an irregular grid based on the "Meduza” technique. Dynamic parameters of matter movement in the volume are obtained for various times. As the computation showed, a vapourgas bubble formed at explosion attracts to bottom and turns into torus extending in the spherical volume surface direction.
