STRUCTURE: One rectangular copper wire mesh is supported by three insulating pillars. The insulating pillar is composed of three parts. In order to increase the stability of the instrument, an iron base is used. The insulating part is made of plexiglass, and the supporting rod part is fixed with the copper wire mesh. , It can be inserted out of the insulating pole to save the box. Red silk threads are hung on both sides of the copper wire mesh. Hang 10 silk threads on each of the three sides of the copper wire mesh with a length of 400 mm.
