Over at the Scientific American Physics Week in Review is a link to a video on the Derek Muller's explanation on the physics behind Kelvin's Thunderstorm.
The setup, also known as a Kelvin water dropper is a system where two streams of falling water use electrostatic induction to generate high voltages across a spark gap.
It's explained further, along with hints and tips on how to build your own, in this article by Bill Beaty, and in this Makezine Article.
Spotted at Scientific American Physics Week in Review. Derek Muller's Veritasium Youtube channel is also worth a more general look if you haven't seen it before.
(No this is not news, but it is cool).

Am I the only one that was annoyed by the editing in that video?

However, the science was a joy to watch. I took physics until (UK) college levels, and I have never encountered that experiment before. I can only imagine in was on the syllabus in the final year of the O-level course, which I missed as for some unknown reason I did a whole bunch of O-levels when I was 14. Even though I've seen it I still can't believe that the initial charge that you can build up from neutral can actually have so much influence on the streams of water to continue the further build-up of charge. I'm genuinely surprised the signal gets above the noise floor.

We should have more articles like this here. Thanks guys!
