it takes me back to my old school days. we had one of these in one of the science labs it was great fun.
anyway it reminds me of an episode of Luis Theroux's weird weekends. when he went in search of aliens. he found a cult who claimed to go out killing aliens and shooting down UFO's on a daily basis, and they built there own anti-alien weapons, similar to the lightning malarky seen in the web page in question.
the episode is on his best of DVD.
