This plasma glass ball consists of a small amount of a noble gas, which can be used to show how a static discharge in a gas appears on ionization. The ionization has been created using the built-in power supply, which produces a voltage of 120 kV with a very low current. The tension graph helps create such high potential that continuous discharges can be generated, as in the glass box, similar to threads of lightning (hence also called lightning ball). The discharge is also done by both touches.
The electrical field that appears outside the ball is very weak, and it is possible to get a fluorescent lamp or a light bulb to lighten slightly.
Ball: Ø = 20 cm.
Hight: 30 cm.
