What does electric curent look like?

[Smugley]

Just for something completely different... I was stunned by these images of electric current from a Van de Graaff generator captured directly onto film, and thought you lot might be interested. Hiroshi Sugimoto’s Lightning Fields | PDN Photo of the Day

Nice one,

Back in the dark ages when I were a lad a mad Physics teacher at school was in love with his Van der graff generator(s); his pi-ece de resistance (sorry couldn't resist (again) the pun) was getting out his massive one (Oo-er missus), standing a poor mis-fortunate on an insulating tray & zapping them for all they were worth.
The inevitable day came when I was dragged to front of class, problem being that my blakey laden spooner (ask your dad) heels were overhanging the tray where-upon 3 inch lightening bolts were shooting to earth Painfull!
