I think this is a very cool effect resulting in highly-visual eye candy. The reason I gave it only 3 stars out of a possible 5 is because of the intentional omission, which is my personal opinion only, and may or may not reflect the actual truth, of a critical factor, an arts-and-crafts skill, needed in the construction of the gimmick. I can not accomplish what needs to be done to make the gimmick. I have tried for many hours resulting in nothing but continued frustration, and the fact that many other people have the same problem as me indicates that I am not the only one. It's a very difficult skill to develop but is absolutely necessary for this trick to work. Maybe you'll be better than most at accomplishing this. Other tricks created by other artists involve the exact same skills needed to produce their gimmick as well. But, those artists do not include this information up front before purchasing. I believe that it is an intentional omission on their part because of the difficulty involved. What a shame. All they would have to do is to include, at the bottom of the advertising for the effect, which would not be divulging the complete method, a caveat for the consumer to consider before purchasing. Inform them that it requires an arts-and-crafts skill which some people find to be difficult to accomplish. That's all. I have several other effects I have purchased which are ingenious in the method, but require a gimmick which the consumer has to make as per the supplier's instructions. Those are all sitting in my magic drawer, awaiting the person who has the acquired skill to fabricate the gimmick and bring the trick to life. Having said that, this is an awesome effect of great value for the little money it costs, which offers a high degree of visual eye candy for the spectator and the belief it imparts that this could only be accomplished by a true wizard. ...
