Although this thread will not be a massive contribution to the advancement of the art or anything of the sort, some responses would be greatly appreciated. I have recently been assigned a history project in which I am focussing on Dai Vernon as my topic. I would like to perform a trick for my class as an aid to the project. If I had time to brush up on my cups and balls routine for instance I would perform that since Dai vernon also did it. I am considering an ambitous card routine however it may be a bit out of scale for a whole class. So my request is that some one would suggest a trick that takes no more than a minute and a half to two minutes to perform, and it be something with a big impact on the audience. This may be a bit much to ask or the wrong place to ask it however I'm in a bit of a pinch and any help would be appreciated!
