Experimental investigation of the plasma, obtained by means of fast discharge in a spherical cavity, is presented. Time developement and some other properties of the plasma balls are studied. The detailed description of the setup is given together with the related experimental methods and technics. The work gives some hints for further investigations. The theoretical modelling of the process of spherical shock wave generation and its cumulation is an interesting point.
