Your recent Origins article ("Ready, Set, Spark!" Summer 2020) stirred memories of my youth. My home was a short distance from Caltech, and I was able to enjoy several of the demonstrations at High Volts, which were just as Royal Sorenson described in 1985. As for the article, the picture should not have been photoshopped! Those slick hairdos are a distraction from the real event. Also, the impulse generator was not rapid! It took many seconds, as Sorenson states, to charge the capacitors for a single pulse.
