Brainteaser Quiz #1!

Here's a quick test of intelligence. There are no tricks to the test, and it looks pretty simple. But let's see how YOU do!

Read this sentence:


Now count aloud the F's in that sentence. Count them ONLY ONCE. Do not go back and count them again. What is your answer? Now, check the correct answer below.

Reveal Answer

There are six F's in the sentence. There is no catch. Many people forget the F in "OF", and that word appears three times in the sentence. The human brain tends to see them as V's and not F's! If you spotted four, five, or even all six, well you beat the average!



Brainteaser Quiz #2!

  1. One day Kerry celebrated her birthday. Two days later her older twin brother, Terry, celebrated his birthday. How could this be?

    Reveal Answer

    At the time she went into labor, the mother of the twins was travelling by boat. The older twin, Terry, was born first, early on March 1st. The boat then crossed the International Date line and Kerry, the younger twin, was born on February the 28th. In a leap year the younger twin celebrates her birthday two days before her older brother. Another option suggested by one of our visitors is that although he was her "twin" brother, he could have been the twin of another sibling.

  2. Manhole Covers: Why is it better to have round manhole covers than square ones?

    Reveal Answer

    A square manhole cover can be turned and dropped down the diagonal of the manhole. A round manhole cannot be dropped down the manhole. >So for safety and practicality, all manhole covers should be round.

  3. The Deadly Party: A man went to a party and drank some of the punch. He then left early. Everyone else at the party who drank the same punch were poisoned and became very sick. Why did the man not get sick?

    Reveal Answer

    The poison in the punch came from the ice cubes. When the man drank the punch the ice was fully frozen. Gradually it melted, poisoning the punch. Alternative solution: He could have poisoned the punch after drinking some of it.

  4. Trouble with Sons: A woman had two sons who were born on the same hour of the same day of the same year. But they were not twins. How could this be so?

Brainteaser Quiz #4

Quiz for people who know everything:

  1. There's one sport in which neither the spectators nor the participants know the score or the leader until the contest ends. What is it?

    Reveal Answer


  2. What famous North American landmark is constantly moving backward?

    Reveal Answer

    Niagara Falls. The rim is worn down about 2 and a half feet each year because of the millions of gallons of water that rush over it every minute.

  3. Of all vegetables, typically only two can live to produce on their own for several growing seasons. Most other vegetables must be replanted every year. What are the two vegetables that are most commonly considered perennials?

    Reveal Answer

    Asparagus and rhubarb


    Note: At the suggestion of a visitor, we checked with Oregon State University's Horticulture Department and learned that in addition to the two most common vegetable perennials, we should probably also consider the Jerusalem artichoke (as it is perennial everywhere) and the globe artichoke since it can be a perennial in areas with mild winters. Plus there are many of the solanaceous crops, such as tomato and pepper, that can be perennials given the right variety and a tropical climate; and horseradish and several herbs might be called vegetables as well. So do not be surprised if you hear other answers to this question!
  4. Name the only sport traditionally played in America which the ball is always in possession of the team on defense, and the offensive team can score without touching the ball.

    Baseball. In some other countries, the answer could also be cricket
