You are standing outside a closed door. On the other side of the door is a room that has three light bulbs in it. The room is completely sealed off from the outside. It has no windows and nothing can get in or out except through the door. On the outside of the room there are three light switches that control each of the respective light bulbs on the other side of the door.
Your assignment is to determine which light switch controls which light bulb. You are allowed to enter the room only once, and once you come out, you must be able to state with 100% certainty which light switch controls which light bulb.
Turn one light switch on, wait a few minutes, then turn it off and turn another light switch on. Go into the room and feel the light bulbs. The one that’s still warm is connected to the switch that you first turned on, the one that is on was the second switch you turned on, and the last bulb is controlled by the switch that you didn’t touch.
A penguin. If all four walls face north the house must be at the southernmost point of the earth. Really, any native antarctic bird would work.
This brain teaser is quite similar to the guy whose house walls face south and sees a bear, then you’re asked the color of the bear. The bear would be white (a polar bear) as they’re the only bears indigenous to the north pole. A lawyer would claim it’s all circumstantial evidence and the bear could be an imported brown bear. The lawyer makes a valid point.
A dear old relative passed away recently and her family gathered for the reading of the will. The final item was the Chalk Emerald, a priceless gem. The will bequeathed it to whoever determined where it was hidden. The only clue was it was in a cylinder surrounded by a thousand squares. A young lass of barely six immediately piped up saying she knew where it was hidden and she was correct. Where was the hiding place?
Mark suggested two alternative solutions: A cylindrical chimney or a well, the squares being the bricks. Although most bricks aren’t square, it’s conceivable I guess.
I’m a five letter word. Remove my last two letters and I’m a synonym of drag. My second and third letters form an exclamation and my first and second letters are a homophone with a number. What am I?
Towel. Tow is a synonym of drag, ow is an exclamation when you’re hurt (and far more appropriate in mixed company than the four-letter alternatives) and to is a homophone of two.
