A seven-year-old kid challenged his classmates that he can make the number one disappear by adding something to it.

How can he do that?

Four men were in a boat on the lake. The boat turns over, and all four men sink to the bottom of the lake, yet not a single man got wet! Why?

This is a simple one. You just have to count the number of Fs in the given sentence.

Finished Files are the result of years of scientific study combined with the experience of years.

How many did you count?

What is always in front of you but can’t be seen?

Who can jump higher than a Mountain?

Can you count the number of squares in the figure below?

Can you decipher these quotes by Albert Einstein?

John left on a horse on Thursday , was gone for two days, and came back on Thursday after completing his work. How did that happen?

Take away the whole and some still remain. What is it?

John is on an island and there are three crates of fruit that have washed up in front of him. One crate contains only apples. One crate contains only oranges. The other crate contains both apples and oranges.

Each crate is labelled. One reads 'apples', one reads 'oranges', and one reads 'apples and oranges'. He know that NONE of the crates have been labeled correctly - they are all wrong.

If he can only take out and look at just one of the pieces of fruit from just one of the crates, how can he label all of the crates correctly?
