Beschreibung:
The critical point in the experiment is that the jet should form drops just as it enters the short metal tube. This will cause a charge separation: if the lower end of the jet is negatively charged for example, then the drops forming at that point will also be negatively charged.
Information and ideas:
Why is there a charge separation?
Can this be compared with electricity generation in the generator?
Category brain twister, conundrum ...
