Frogprince, "skeptical" means "refusing to believe without evidence". Not evidence of why (FWIW, acupuncture still hasn't got that), but just evidence that it *does*.

As far as this mythical Russian's encounters with the "High Priests" of science, I call bullshit. For starters, any sane person would realise how many cranks there are. You want to show off something extraordinary, you'd better do it in person. And for another thing, why go to scientists? This isn't like it needs some special scientific skills - any munchkin can see you flying, so any journalist would do just fine. And James Randi famously will pay $1m to anyone who could do that.

FWIW, I'm tempted to set up the folded-paper experiment as described, just to disprove it. See if I can find some free time.
