This is the first interactive book of magic tricks in which the book plays the role of the magician and the reader experiences magical revelations as he or she scratches off the scratch-offs. The reader thinks of a word, a number, or a picture on the page and magically, their thought is revealed when they scratch. Highly recommended for the young and young at heart from 10 - 100 years of age. Written by professional magician and former mathematics teacher Danny Orleans, this book celebrates the relationship between magic and mathematics as the former uses the latter (in most cases) to make the magic happen.
