I still go back and watch it about once a year. The only maker in my high school was way into Tesla coils, and I have been Team Tesla (Tesla vs Edison) from the first short form biography of Tesla that I read.
One of Tesla's craziest inventions, to my mind, was discovering that, given the right conditions, a human can survive both high voltage and high current. He developed circuits to increase the frequency of the electricity (I believe a version of that strategy is applied here?), and if the frequency is ridiculously high then the skin effect puts the electricity into your epidermis only. Wikipedia says that 1GHz in copper is 2μm https://en.wikipedia.org/wiki/Skin_effect. I sincerely hope nobody has measured this in human tissue.
Reportedly, it makes you tingly.
This invention is bittersweet to me, because I feel this also marks the beginning of Tesla's transition into canonical Mad Scientist. He figured it was therapeutic and exposed himself to these fields routinely.
