Pick your brain
Adam came home from Switzerland for the summer. I was ecstatic to see him, since I haven't seen him since Christmas. My parents and he came out yesterday and we went out to dinner at Nakama. For you Pittsburgers who enjoy fine sushi, theirs is awesome! If you like your food actually warmed and cooked, they have hibachi grills where they cook in front of you as well. There’s a little bit for everyone!
Today we went to the Cheesecake factory- more aesthetics than fine food, but it was still abundant and tasty. While waiting on our food to arrive, we killed some time by mapping out a hiking route and solving some brainteasers. Here's one:
As a form of torturous death, a central American native tribe buries its captives in the sand with only their heads exposed. They die an unpleasant death in the heat. Upon capturing four intruders, "Bob", a restless native decided to present his victims with a puzzler. If they solve it, then they may go free. Bob buries all four in the sand, with only their heads exposed. Three, he places on one side of a large wall, and one he places on the opposite wall. The three on the same side are buried facing the wall, one behind the other, all in the same direction. He has four hats, two white, and two black. He places one hat on each head of his Easter Island imitators. He tells them that without talking, motioning, or using any other form of communication, they must tell him, with absolute certainty, what color hat he or she is wearing.
After five minutes, one of the talking heads pipes up and declares the color of his hat. He is correct and they are all free.
How does he know the color of his hat?
A few disclaimers:
The wall does NOT have any windows, it is not transparent, and they cannot see over/around it
No one can see his or her own hat; It is too small. Lets pretend its a yamica.
If you know the answer, post it, I'll let you know sooner or later how the hat color is determined.
