c) If die same question is addressed to the Truth-teller and he has the object, he must answer, d) Likewise, if the Truth-teller docs not have the object, his answer is uYcs.J> 4 .

So in either instance the person with the object always answers- "No," and the person without always says, "Yes," regardless of whether they 3 re lying or telling the truth.

Such being the case, it doesn't matter whether you address the question to the Liar or to the Truth-teller. If the answer is yes, that person docs not have the object; and if the answer is no, they do. It sounds simple when someone explains it, but believe me, it can be dioroughly cnnfoundir.g to most people, if thev don 11 already know the answer.

effect: So much for fundamentals. What I have done is to build on Kosky s idea in several ways.

First, instead of using two people, 1 use a single^spectator and haw her mentally nominate one of her hands to be the Liar arid the other the Truth-teller. She then takes a coin and holds it behind her back. In this position she passes the coin to whichever hand she chooses and brings out both tighdy clasped, so that no one knows the location.

1 then ask her to raise one hand and, if it is the "Liar hand," to lie; and if not, to be truthful. 1 then inquire if the coin is in the uLiar hand." And the answer identifies its real location.

Sometimes, to make the thing more impressive, 1 use three volunteers and repeat the divination with each in turn. Here is how 1 build the drama.

ME'lHOD AND PrESENTATTOX: Three women {i always use women for this; are invited to join you in front of the group, and are shown a cookie can filled with quarters. "Will each of you please take one coin from fJ)e container."

When this has been done you continue, %tWe are going to do an expert-ment that urill require your toud attention. First, let's assume that each of your hands is a person in its own rigfit. One is completely truthjvl; the other is a total liar who netrr tells the truth. If J said to that hand Are you a liars' the hand ivould ansiver, 'No,' because it always lies. Now, will each of you decide in your mind which hand you watu to be which. Dont tell anyone else, not even one another. Just keep the secret to yourself

*"Whenyou have reached your decision, fix it firmly in your mind Then place your hands behind your backs and move the com to either hand When you have done so, make both hands into fists, so that no one can tell which holds the coin, and bring them out. "
