I was browsing around James Randi’s site and came upon a reference to a levitation trick, described by Randi thusly:
I’d never heard of this before. It was asked about here a couple of months ago, and the asker was directed to do a websearch for “light as a feather stiff as a board”. I did so, and found loads and loads of instructions of how to do the trick, but none that explained how it worked (apart from one seriously goofball theory regarding biomagnetism, which claimed that the liftee had to be facing West for the trick to work). I understand that each person lifts only 25% of the person’s body weight, but that’s a lot to lift with one index finger…
Anyone care to explain?
