by Martin Gardner

Published 31 December 1999
Can you really predict what your friends are thinking--the numbers or letters or words they come up with--and don't tell you? With this extraordinary book, you can do it! Many of these feats of mental magic will always come out right--some of them will do it almost all the time. You'll amaze everybody--and never tell how you did it. * Enter your age in a calculator. Multiply it by 12. Add the mysterious number 2856. Divide by 3. Divide by 4. Subtract your age. What number is now on display? * Toss three dice on the table. Call them A, B, and C. Write down the total showing on A and B. Turn B and C upside down and write the total showing. Turn upside C and A and write the total. Add the three sums. What's the result? Answers: the number on display is 238; the result is 21. The author lives in Hendersonville, NC. 96 pages, 5 3/8 x 8 1/4.
