You are in a room that has three switches and a closed door. The switches control three light bulbs on the other side of the door. Once you open the door, you may never touch the switches again. How can you definitively tell which switch is connected to each of the light bulbs?
Answer: Turn on the first two switches. Leave them on for five minutes. Once five minutes has passed, turn off the second switch, leaving one switch on. Now go through the door. The light that is still on is connected to the first switch. Whichever of the other two is warm to the touch is connected to the second switch. The bulb that is cold is connected to the switch that was never turned on. Thought this brain teaser was hard? Almost no one gets this logic card trick right.

An Arab sheik is old and must leave his fortune to one of his two sons. He makes a proposition: Both sons will ride their camels in a race, and whichever camel crosses the finish line LAST will win the fortune for its owner.
