Answers to brainteasers
1. The answer is "ONE WORD."
2. The solution to this puzzle involves breaking out of the mindset that you will immediately go into the room and look at the
three bulbs. The puzzle leads you to this assumption with words like "light bulbs," "lights" and "turn on." But what about
using your other senses?
What about your sense of "touch" in addition to your sense of sight? The answer is to turn on two switches for 10 to 15 minutes.
Then turn one of them off, and immediately go into the room where the light bulbs are located. The switch that you left on
controls the light bulb that is still producing light. The switch you turned off controls the light bulb that is warm. The
third switch controls the light bulb at room temperature. Then touch the other two bulbs.
3. In this puzzle, the five seemingly unrelated objects have in common the parts of a human's or animal's face. Cannons have
mouths; footballs have a nose (as in he made a touchdown by the nose of the ball); gears have teeth; potatoes have eyes; shoes
have a tongue; corn has ears; and pliers have a jaw.
