Hey, I want to present my latest project, intended for the physics lesson. I used high voltage transformer from some very old tv. The design produces a much higher current frequency (~50 kHz) and voltage (~10 kV). Such frequency causes that project is 'rather' not dangerous.. ;P
Some pics:

whoah cool :D
Did you figure it yourself, or is there some schematic available?

I did it with schematics  ;D For oriented in such things:

Description on this site is in polish, but you can try to google it. It's based on ne555 circuit, irf540 transistor, and high voltage transformer from old tv.
It requires a lot of work, but final effect is.. electrifying :D

Yeah... I'll try that some time in the future :D
Not that much of an electromechanic.

That is freaking awesome :D,  those things define my childhood :D
