Ok, some parts you probably should get are: 1. neon sign transformer, 15kv 2. heavy gauge insulated wire (probably a bit thicker than double strand wire used for lamp power cords). 3. 3 foot length of 1 1/2 diameter pvc pipe 4. very fine motor wire, shellacked (sp?) this wire is like the wire used to wind electromagnets 5. 1/4 inch plate glass, 5 sheets or so, about 16" x 22" 6. plastic container for plate glass, one of those under-bed containers will do 7. motor oil, 10W-40 is ok 8. misc parts Wind the fine wire around the pvc pipe, it takes a few days usually, single layer Wind some of the thick wire around a quaker oats round box make a capacitor by putting tin foil sheets, with rounded edges, between the plates. immerse the plates in the oil, getting out bubbles hook up the transformer across a spark gap to the plates, which are in parallel with the primary winding (thick wire). put the pvc pipe with the fine wire upright and inside the quaker oats box with the primary Ground the lower wire of the secondary (fine wire from pvc, the wire on the lowest part, where you started to wind the wire) to a pipe or some suitable ground Turn on the transformer briefly; don't look at the spark gap because too much ultraviolet radiation it is loud, will interfere with radio, tv, cable, etc. > There are some equations, if I recall cost is maybe 50 to 100 dollars there are plans for a parlor-trick size device in the book _Build your own working laser, phaser, ion ray gun_ that can be readily scaled up Good luck WARNING: if you have a cat, a curious cat, make sure it stays away from the apparatus or else all that will be left will be a wisker, and your next project will have to be a crystal radio > In article <4o4486$n67@carbon.cudenver.edu> you wrote: > > : Ok, I made one that put out 2 foot sparks. > > : Now is time for the grandaddy of them all. > > : It should not be operable indoors, for obvious reasons. > > > : How?
