Water bending with comb: but where do the electrons go?

[QUOTE="Orthoceras, post: 6438320, member: 351545"] Right That is your hypothesis. However, [URL='https://en.wikipedia.org/wiki/Kelvin_water_dropper']wikipedia[/URL] says "When a drop breaks off the end of the left-hand stream, the drop carries a negative charge with it" Your hypothesis that the left stream and the right stream are neutral (everywhere uncharged), implies that a kelvin water dropper could be fed by two separate water bottles, insulated from each other. However, in reality the streams must be electrically connected. Above the height where the streams form droplets, the water is a continuous conductor from left to right, and the ions are the charge carriers. The situation is somewhat similar to electrostatic induction in an electroscope, if the table is approached with a positive balloon, the table becomes negatively charged, and the leaves become positively charged. If a leaf would fall off, it would still be positive. For the same reason droplets in the kelvin water dropper are charged, due to induction by the so called "induction rings". [/QUOTE]
