      A number of papers stated that during charge explosion in fluid a vapour-gas 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 two-dimensional 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 vapour-gas bubble formed at explosion attracts to bottom and turns into torus extending in the spherical volume surface direction.
