An impromptu curiosity that will leave your spectators scratching their heads!
VERTICAL begins by showing an arrow drawn on a piece of paper. A few simple folds and unfolding and the arrow still points upward. When a spectator tries the same thing, you have them imagine the arrow pointing downward, and when they unfold their paper, it is! A perfect impromptu puzzle that requires no sleight of hand!
