The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
better idea, use a MOT and car battery and a brick 300A IGBT with control sircute and step 12VDC to 120VAC then another MOT to 2KV. presto you have a portable MOT hv setup try that on your class. lol

I then rectified my little relay generator to charge three parallel 1.5uf 400V poly caps, later I found it overcharged them up to ~1kV and I used this to make loud bangs on all metal objects around me such as door handles, metal parts on school desks etc. then there were black dots on all these objects Later my physics teacher prohibited me from bringing it to school, so I replaced the caps with a 6800uf 50V lytic (safe), this made even bigger black spots and you could discharge it through tin foil several times on one charge while making flying sparks, ehh good old times :)

OO! good idea. I'll have to finish my little camera-flash CW multiplier first though. After that, asemble a cap bank that can take the rectified output (I think my CW has 3 stages, so that would be.... something like 1080 volts? I can;t remember the formula for CW multiplication...)Hmm.. Anyone got some high-voltage caps they can spare? cause I doupt that radioshack will have what I'm looking for... But before all this, I'll have to get my mom to drive me down to radio shack for some more desoldiering-braid or a solder-sucker.
YEESH! the parts for the voltage multiplier section are going to cost me over $50.. Oh well, just few more weeks.. Maybe I could just use some camera flash bits, cause I've just spent all my cash on an iggy coil setup :) can't wait to get that done!

A couple of years ago I also made one of those shockers :) It had a 555 timer and a power transistor to oscillate switch the power for the transformer at a frequency of ~10Hz. I've also tried the self-oscillating relay thing and got ~5mm sparks with a 230V/10V transformer. It ran at its best at ~60Hz. Maybe the kickback of the relay's coil rose the voltage or something. That by the way works only with particular relays.

Just a little inductive kick shock generator UPDATED
and I used this to make loud bangs on all metal objects around me such as door handles, metal parts on school desks etc. then there were black dots on all these objects
