This is a beautiful little demonstration dating back to to Lord Kelvin. Using a few cans wires and dripping water it is possible to generate thousands of volts in a beautifully elegant piece of physics.
Read more about this experiment.
Garage science is a blog of science experiments you probably can't or shouldn't do at home

Shouldn't the top two containers be connected together too?

Yeah. And infact they are. Both are sitting (as far as I recall) on a sheet of aluminium which you might just be able to see looking at the set-up in the photo, forming the connection (the paint having been sanded off the bottom of the pots). You could equally use a single trough of water with two taps out of it. An extra wire ought to be drawn in...

You are of course right, I have now updated the diagrams

"Electrons in the water are attracted by the positive ring, so the drops which are just forming in this ring become negative and then fall into the pot below. "
If the positive ring is attracting electrons from the water, shouldn't that leave the water drops with a positive charge? Or are we looking at ionization of the air within the ring (positive ions sucking electrons from the water)?

Scuse me,
Is there a way to harness this 1000v energy?

I want to know how we can measure the voltage in this equipment(Kelvin's water dropper)

I think it is important to mention that the effect is due to Electrostatic Induction ( see

).

Hello i was wondering why my Klevin Water dropper is not working. I have practically copied the model in the video except my drippers are 50ml glass burets (large pippets) and i have a wire attaching these together they then drip down through my inducers (coat hanger wire) to my collectors which are baked bean tins with an alumnium false bottom which i added due to the plastic lining on the inside of the cans also i have done the experiment in the souther hemisphere with aproxx 60% or less humidity and i dont know if its my flow rate thats the promblem or what also i checked for shorting with an am radio but there wrre none also i was aproxx getting 1.5 dropps per second
thanks if any one has a solution please contact me on aj_wild@msn.com

The water holding containers and droppers can be made from electrically insulating materials and not connected to earth provided there is a water path connecting them allowing ions to flow from one dropper to the other as in a variant I have made.
