I know its a little off topic, but I approached you for help a few years ago about a science project and you were just an amazing resource. For me science projects have always been about building something, and taking it to the extreme. Since ive already done a tesla coil, a coil gun (unsucessfully, the next logical step is to make a Van De graff. I was wondering any sites you have or info, because it seems to be slightly scarce, online atleast. Specifically, for this thing to be massive, as I hope it to be (and I do realize the dangers of it at these sizes), what would you suggest using to form the ball from, and what are your thoughts on sizes of the ball, also, I dont know wether or not to use a transformer to power it or not, as I understand, as long as the ball is of sufficent size, It should not make too much of a difference. Thanks in advance.
