WARNING! - If you try this experiment, you may get a lightning strike.
The electrostatic polarity detector can be used as a lightning strike detector.
Recently, lightning strikes frequently in the neighborhood due to atmospheric instability.
So I installed an electrostatic polarity detector outside the window.
The electrostatic polarity detector turns on when a lightning clouds getting closer.
Experiments show that lightning has two polarities.
