These guys get to play with stored energy in a different way than we did back when one would have a class mate toss you a charged up capacitor for shits and giggles. https://www.youtube.com/watch?v=xlzIUKyA1eQ

I was developing a 50kV supply for an X-Ray machine once and one of my co-engineers did a demo for us. We test un-potted in a Fluorinert bath. He took a long stick and placed a rounded nose "probe" on the end of it and a long HV wire to ground. As he approached the energized supply output buried in the bath, the bath started jiggling furiously on the surface. He still had to immerse it though to get the arc for the shutdown test, but that was the first time I saw an arc through fluorinert, because it has a really high dielectric strength. Then, he placed a sharpened nail on the end of the stick. It was amazing how vigorously the bath was aggitated as he approached it. And then I saw another first. A 50kV arc up and out of the bath and through the air to this very high attraction gradient "ground point". It was a couple inches through the bath and then a couple more inches through the air. Amazing. Shutdown circuit works.

Makes me wonder if a circulating loop of Fluorinert or SF6 could be used to replace the belt in a Van de Graaff machine. Some quick Googling suggests that this is indeed a problem in the petroleum industry. In one study they pulled 6 microamps of ground current out of a gas pipe, and that was without intentional charge injection: https://nvlpubs.nist.gov/nistpubs/jres/69C/jresv69Cn4p307_A1b.pdf Everyone who has played with a VdG will understand the desire to get rid of the belt. 6 microamps is well within the ballpark. -- john, KE5FX

The Boston museum of science has an example of a similar event full-scale, "petrified lightning" where an arc has blasted along a beach, instantly glassifying the surrounding sand into a hollow tube. I guess it's called "fulgurite": <https://www.researchgate.net/figure/A-display-describing-petrified-lightning-and-fulgurite-at-the-Boston-Museum-of-Science_fig1_301766309>
