Lichtenberg Figures in Crookes vacuum
These figures are unfortunately unclear due to the near
impossible circumstances of trying to photograph them -
they were created using a burned out Edison bulb with
a straight filament. The filament heavily bombarded
was spinning around the tube, and when it hit the glass
formed rapid moving Lichtenberg Figures.
