Ed Burger, co-author of The 5 Elements of Effective Thinking, spent the day at this leadership workshop at Eastern Michigan University. The assembled group solved creative puzzles using the skills found in the book. Put your own skills to the test with this mathimagical puzzle:
What’s black and red and magical all over?
Consider the following mathematical illusion: A regular deck of 52 playing cards is shuffled several times by an audience member until everyone agrees that the cards are completely shuffled. Then, without looking at the cards themselves, the magician divides the deck into two equal piles of 26 cards. The magician taps both piles of face-down cards three times. Then, one by one, the magician reveals the cards of both piles. Magically, the magician is able to have the cards arrange themselves so that the number of cards showing black suits in the first pie is identical to the number of cards showing red suits in the second pile. Your challenge is to figure out the secret to this illusion and then perform it for your friends.
Post your best guess below.
