600kV from 6 “C” batteries

More striking than this image (from jurvetson’s flickr photostream), in which 6 “C” batteries are used to generate an approximately 600kV mini-lightning strike, is the way that the flickr is used to annotate parts of the image (“notes”) in the original site. I can imagine biology students labeling parts of animals from photos or anatomy students marking up photos of operations. Clearly, it even has use in physics. And jurvetson kindly provides an explanation of how it works with a link to Wikipedia on the Marx generator. At one level, one could consider this an extreme automation because a student could look up Marx generator and find more information about it–nevermind that they wouldn’t. However, this differs from a conventional “check out this cool photo” by the presence of metadata describing information that most students wouldn’t have been able to recognize unless they already knew what a Marx generator was, making this a nice example of information.
