I actually got this for a grandchild who is into magic. We went over the directions and procedures a few times and she got it very well - she's only six. She tried it out on someone and they were amazed. My only suggestion for this trick is that it should NOT be done with the observer in close range or the film that can come loose can show easily. One thing that I had my granddaughter do for extra effect was to cut out several more pieces of plain paper to feed through the Money Maker, but first, to have the observer write her own name on the piece of white paper. Then my granddaughter offered to get back the paper with the signature on it and the observer was hooked, saying, "Yes!" She fed the dollar bill back into the Money Maker and Voila! back came the white paper with the observer's signature on it. It was a hit, and soooo easy to learn to do that a six year old can effectively do the trick - along with a magic want, of course - one that changes colors. But that's another story. This is a great little trick. Just be sure that your observer keeps his/her distance.
