“Invisible Electrostatic Wall” at 3M adhesive tape plant (1996)
Bill Beaty's site was and still is amazing. It sparked my interest (and lifelong hobby) in high voltage back in the late 90s. Some of his essays (and ascii) art explaining concepts like coherence (<a href="http://amasci.com/miscon/coherenc.html" rel="nofollow">http://amasci.com/miscon/coherenc.html</a>) still stick with me today.<p>As for the electrostatic wall story... it's fun but I don't believe it.
