Three mental effects by this young Israelian magician. Two of these use the "dual reality" concept and are quite interesting, the third one is a technique for a peek. While this peek is interesting, it is not hearth shattering. However, the effect that goes with it provides a good way to justify the writing. The book test (first effect) is a very clever use of the gimmick to force word - I never thought about this kind of use. The last effect is more a dissertation on modern (mentalistic) presentation of the Invisible Deck. I don't terribly like Harel's effect, but I'm intrigued by the idea. I think I can use this idea.
