My friend kept a terrarium with a few rocks in it and nothing else. As I recall, it had something to do with levitating the rocks. And this guy was an equipment maintenance technician. Had to be a lot of cognitive dissonance going on in his head.
I knew a guy who had a similar background. Wired a bunch of electronic equipment together. He had a lot of oscilloscopes running like the opening of the old Outer Limits TV show. He claimed he was detecting tachyons and could use them detect nuclear stockpiles remotely no matter where they were. Listening to him was like listening to Star Trek & Babylon 5 technical chatter.
We didn’t fund him.
