I recall reading once that, had Franklin conducted his famous lightning experiment as he described it, it would have likely killed him...  Not that I'm going to duplicate it to check either way...

At the very least he was insulated ... or conducted it from a safe distance, not like the patriotic drivel pictures we were given.

Here's a good account of Franklin's experiment:

He was indoors when he was flying the kite, IIRC.

Your kite is so small ... did you hire the Spinal Tap choreographers?

It only looks small because it's so far away...

I'll have to dig out the video I shot about ten years ago; there was quite a storm in the area and I was shooting the lightning, and completely by chance happened to catch the entire life cycle of a bolt.  In the space of about 20 frames there was one frame with the You are not allowed to view links.

All of that in less than a second.  Alas, not in glorious HD, but I caught it.  :)

These are dangerous to airplanes and re-entering space craft.  The ionosphere needs to discharge, too.

In Unbelievers slow motion film, aren't those ball-lightings forming in the path of the main bold?

Yeah, and apparently the first one to contact the ground gives a path to the rest of the bolt.
