*Subject: HV Cap Fun! * * I just picked up a couple of 14ufd 25KVDC caps and am looking for something *to do with them... I'm looking for good demonstations, experiments, etc. *I figure these guys could be used for a nice spark-gap demo or perhaps *vaporize wire. * * If you've got any ideas, let me know! Here at work they keep electronic parts in "anit-static" plastic bags. There are a couple of varieties-one of which is a plastic coated with a vary thin (somewhat transparent) layer of nickel. While 25KV will normally arc about 1/2 inch-it can create an arc about 10 inches long over the surface of one of these anti-static bags. After you have done this hold the plastic up to the light and you can see the tracks from the arcs: they vaporize the metal off of the plastic.
