The principle of anti-static ball
Due to the needs of the ion accelerator, Van de Waff invented a new electrostatic generator called the electrostatic ball. It can generate very high voltage (200Kev), so it is treated as
As the DC high-voltage power supply of the ion accelerator, the static electricity generation source has frictional electrification, and is directly charged with two types of voltage.
The principle: the insulator and the metal frictionally electrify and can carry electricity: the motor drives and the belt and the metal brush frictionally electrify,
In the aspect, the belt is transported to the upper metal spherical shell, and the electric charge generated above is also transported downward. On the other hand, the metal brush of the base is grounded to guide the accumulated electric power.
The electrostatic ball should be plugged into the power supply (220V/110V), the hand is put up and the high voltage static electricity in the ball is generated, which is low in the ball.
A discharge spark is generated in the pressurized gas to form a strip of colored light.
The experimental device consists mainly of two parallel conductor plates placed vertically and a metal plated table tennis ball suspended between them. During the experiment, two conductor plates were connected to the positive and negative electrodes of the high-voltage electrostatic power supply. When the high voltage power supply is turned on, an electric field substantially horizontally is generated between the two conductor plates. Gently push the insulated thin wire hanging the table tennis ball so that the table tennis ball touches a certain plate. The table tennis ball is charged with the same electric charge as the plate symbol it touches; While rebounding and repelling, under the action of the electric field force, it flies to the other plate. When it contacts the plate, it first neutralizes the charged charge, and at the same time carries the same charge as the newly contacted plate symbol. The same charge is repelled, and table tennis is bombarded again.
Back to the repulsion, under the action of the electric field force, the table tennis ball flies in the opposite direction, and the above process is repeated at the other plate. It back and forth collides back and forth, while transferring charge, the source of energy is a high-voltage electrostatic power source connected to the plates. 
The electrostatic field's work on the live ping pong in the flight complements the energy consumption caused by the air resistance factor, so the hopping back and forth between the two pole plates can continue.
