There are several xkcd lightning entries. #260 is the closest to fulgurites, and there are also #795 and #242.

no the point was the bitchy snotty wife returns home to get divorce papers signed and turns back into a human being. One of the devices used was the husband got his crap together and started pulling flawless blown glass sculptures (that IRL cost thousands of dollars) out of the beach like seashells. Its not a terrible movie, but its still pure crap

I prefer Thunder Nuggets

Martin Uman did similar work in Florida I think.

I might have a spool of wire go into a bucket of pure silica….a big model spaceship filled with explosives in front of a green screen…

…and now I’m calling them “static poops”

Isn’t there a movie about an artist that does this? Sweet Home Alabama I think it was.

Oh wait, that wasn’t the point of the movie? Growing up my sisters watched that a few times. The fulgurites were the the best part of the movie.

Don’t need the spool of wire — the researches at South Dakota School of Mines regularly use rocket exhaust as the initiator/attractor for their lightning strike research.
