What happens when magicians learn the methods to tricks? We get paranoid that laymen will also learn
the method so we try to invent other/"better" "more natural" methods. 1000 methods to do one trick
when you only need one good method, so diabolical that no layman would ever think of it. This is not
that. I prefer Richard Osterlind's stainless steel blindfold. All a layman would have to do with
this tin foil blind fold thing is try it and they would figure it out.
