Experimental Research on Ball Lightning
Experiments on producing ball lightning (fire balls) were made with electric discharge in fuel gas and/or aerosol. A long lifetime fire balls (1 – 2 s) were observed in 2.7% ethane and cotton fibers (100 cm3.) In other experiment, plasma fire balls were formed in the natural atmosphere by the interference of the microwave (wave length being 12.2cm, power ranging 1kw – 5.0kw). This is the first confirmation of the possibility of the ball lightning formation proposed by Kapitza. We also report other properties of these fire balls formed in our experiment.
