# 85 Brain Teasers That Will Honestly Probably Melt Your Brain

See if you can make it through all of them, because I couldn't.

## 1.What word in the dictionary is always spelled incorrectly?

The word "incorrectly" is always spelled "incorrectly."

## 2.A doctor gives you three pills and tells you to take one every half hour. How long do the pills last?

The pills last one hour: You take the first pill, wait 30 minutes, take the next pill, wait 30 minutes, then take the last.

## 6.You're running a marathon and you just passed the person who was in second place. What place are you in now?

You're in second place.

February, because it's the shortest month.

A coin

## 13.Jane and Bob have four daughters. Each of their daughters has one brother. How many children do Jane and Bob have in total?

Five children

## 14.How many people is "two pairs of twins twice"?

Eight. If you thought the answer was 16, you are not alone. But a twin is only one person; a pair of twins, just two. Two pairs of twins equal four. Twice that is eight.

## 16.The three volumes of Lord of the Rings sit in order on a shelf. Each is 1 1/4 inches thick, comprising an inch of pages and 1/8 inch for each cover. A bookworm bores from page 1, Volume I, to the last page of Volume III. How far does it travel?

One and a half inches.

Seems like it should be 3 1/2 inches, doesn't it? But if you think about where page 1 of Volume I is when the books are lined up the usual way (Volume I on the left), you'll see that the worm actually passes through only one volume's worth of pages.

## 17.A pencil with a pentagonal cross section has the maker's logo imprinted on one of its five faces. If the pencil is rolled on the table, what is the probability that it stops with the logo facing up?

Zero percent. The pencil will always land with a face of the pentagon down — and thus with an edge, not a face, pointing straight up.

## 19.A visitor points to a portrait on the wall and asks who it is. "Brothers and sisters have I none," says the host, "but that man's father is my father's son." Who is pictured?

The host's son.

## 43.An electric train is moving north at 100 mph. Which way does the smoke blow?

Electric trains don't blow smoke!

## 47.One carafe contains a liter of wine, another a liter of water. A spoonful of wine is moved from the wine carafe to the water carafe and mixed in. A spoonful of the mixture is then moved from the water carafe to the wine carafe. Is there: more wine in the water carafe than water in the wine carafe; more water in the wine carafe than wine in the water carafe; or the same in both?

Same in both.

It seems like, since you transferred pure wine to the water and only a mixture back, there must be more wine in the water than water in the wine. But that can't be right, because then you would have increased the total amount of wine! No matter what you do, if you end with a liter of liquid in each carafe, there must be the same amount of wine in the water carafe as there is water in the wine carafe. The flaw in the first argument is that although you transferred less than a spoonful of water to the wine carafe, you returned some of the wine.
