@SwiftOnSecurity Static electricity is another weird one, I worked on a solar powered research device years ago that would slowly build up static charge until the whole thing just stopped working. We ended up installing a ground connection that fixed the issue but before that we'd just have to let the thing kind of sit for a while to discharge between tests.
@crumbcake @SwiftOnSecurity reminds me of the “magic/more magic” switch: http://www.catb.org/~esr/jargon/html/magic-story.html
