Xmas Tesla Coil
The picture above is what happens when you put a Christmas decoration on a tesla coil, not one of my solid state coils you understand but one of a much older design the kind of thing the great Tesla himself would have made, driven by a spark gap. One of the newer transistor ones would probably get damaged, where as this one is more robust, if the column were strong enough you could probably sit on it with out doing breaking it.
