説明
Four scientific demonstrative presentations concerning a lightning are presented in this article. All presentations can be easily performed on the scientific events held in educational and/or research institutions, such as university, college, research center, elementary, secondary and high schools. The first topic is long gap discharge which shows the model of the lightning from lightning clouds to ground. The high voltage is generated using an impulse voltage generator, which consists five capacitors, gap switches, and dc high-voltage power supply. Human shaped wet sponges were employed in the presentation as a human-body. The second topic is turning-on a fluorescent lamp without direct power supply using Tesla coil as electromagnetic wave radiation source. We show not only some commercial products of Tesla coil but also show how to construct the Tesla coil with much higher output voltage than the merchandise. The third demonstration is a ball lightning using a microwave. Finally, we show a handicraft of small lightning generation on the name card using a piezoelectric crystal in an electric throwaway lighter.
