Time Element Cylinder by Lubor Fiedler
A match is hidden in one of two identical brass tubes. These are put in the pockets. You are now in another room. Obviously you have no clue which of the two tubes the match is in - seen nothing, felt nothing, heard nothing...
Of course, you still name the correct container!
Thanks to a devilish principle that is completely inscrutable. Typical fiddler... With German instructions!
