Riddles
1. Eskimos are very good hunters, but they never hunt penguins. Why not?
2. If boiling water is poured into a thick drinking glass as well as a very thin wine glass, of the two, which is more likely to crack?
3. A soldier has been captured by the enemy. He has been so brave that they offer to let him choose how he wants to be killed. They tell him, "if you tell a lie, you will be shot, and if you tell the truth, you will be hanged." He can make only one statement. He makes the statement and goes free. What did he say?
ANSWERS AT THE BOTTOM
ANSWERS:
1. Eskimos live at the North pole, penguins at the South pole.
2. The thick glass is more likely to crack since glass is a poor conductor of heat. In a thin glass, the heat passes more quickly from the glass into the surrounding air, causing the glass to expand equally. When hot water is poured into a thick glass, the inner surface expands, but the outer surface does not. It is this extreme stress on the glass that causes it to crack.
3. He said I will be shot. If he were shot it would be the truth and if he were to be hanged it would be a lie so they set him free.
