My magic is to show audiences the paper that cannot be shred. To make the trick successful, the first step is to prepare two pieces of small square paper with the same size and same color. Then twist one of the two pieces of paper to make a spitball and hide it into the palm. These two steps are the preparation work before sitting in front of audiences. Then, face the audiences to show them the other piece of paper. Shred this paper, while paying attention to the movement range and not to let the spitball made before drop out of the palm. After shredding the other paper, carefully change the places of the shred paper spitball with the one that is intact and hidden in the palm before. The movement of switching places should be careful but no too slow in the case to be seen through by any of the audiences. Then, gradually unfold the spitball that has been prepared previously and to make the audience wonder why the paper is back to become a competed paper again. This magic makes full use of audiences’ “misdirected assumption about reliability” mentioned in the Tufte reading material to successfully daze their attention.
