They call this The Ultimate Levitation Principle. I think they are overestimating it. The idea is really good, the gimmick is easy to make and chances are you already have the material at home. You don't need to use the item he shows in the video. The problem I have with this item is it is vey angle senstitive and you really do need to have a dark background or people will see the gimmick. The video is not of the highest quality. I bought mine awhile back and I cost me 18.95. For the price they are selling it for now it is worth it. If you do it correctly you get good reactions from people. It is very impromptu. Can be done walking around. THere are better levitation effects out, that get better reactions. THis is good for a beginner.
