Tesla Coils

[DanL]

They're toxic?! hmm, that could be a small problem. I know people who have emptied out the innards into a cannon and shot it off... nice magical mist...

Innards in a coke bottle would, well, make it visible at night. Imagine taking a nice serene walk through the neighborhood one late summer evening, fireflies dancing, evening sprinklers on, just you and - BOOM! Look above you and something glowing bright green blurs above your head and two kids are screaming, "Heads!"

Of course, shooting it off in the middle of a neighborhood is just asking for a bill for fixing someone's house, window, car, cat...
