ATTENTION, this experiment must not be copied, wrong execution is lethal!
In this experiment a test person is electrically loaded.
The electric circuit by the body of the test person must not be closed.
The test person has to be electrically isolated from the remaining environment.
There is only the connection to the high voltage source.
When the high voltage source is activated, the person gets loaded.
(Caution: The tension should be increased slowly
in order to minimize the charging current to the body of the person).
A capacitor is formed by the body of the person on one end and the earth on the other.
On the body of the test person the electrical charges collect themselves.
Since same charges repel themselves, it comes to the effect that the hair is standing up.
