How can I ground a Tesla Coil if I don't have access to the ground outside? Answered
For a project in school, and as part of a speech I'm delivering on Nikola Tesla, I had hoped to have a relatively small Tesla Coil to bring in and show off. The only trick is, the classroom is on the second floor, there are no windows, and it just today snowed where I live (so taking the demonstration outside doesn't seem like a good idea)... So I have really no idea how to ground the secondary on this beast.
I've read a lot about Tesla Coils and seen a lot of schematics, but nobody can give me a good answer for grounding them except for "drive a metal rod into the ground". And despite that, I see videos on Youtube of small tabletop coils (of the scale I wish to build) that don't appear to be connected to anything as a ground other than the mains outlet.
