There is something which you can be arrested for attempting but not for successfully completing.

I have lakes with no water, mountains with no stone and cities with no buildings. What am I?

A word I know has six letters it contains, remove one letter and 12 remain. What is it?

I have branches, but no fruit, trunk or leaves. What am I?

You need to pick one entry from pot A and one from pot B to have a perfect match. Can you do it?

How much will a 38° angle measure when looked at under a microscope that magnifies ten times?

What 8 letter word can have a letter taken away and it still makes a word. Take another letter away and it still makes a word. Keep on doing that until you have one letter left. What is the word?

I travel all around the world but always stay in the corner. What am I?

We are a group of eight brothers. We consider the weak, yet we protect the king in every battle. If we move ahead, we never turn back. Who are we?

These types of puzzles are known as charades. What you have to do is to find two words that are referred to in the first stanza and the second stanza and put them together to form the third word in the third stanza.

Just for example, if my first refers to 'off' and my second refers to 'ice', then my whole will be the 'office'.

My first is present - future's past -
A time in which your lot is cast.

My second is my first of space
Defining people's present place.

My whole describes a lack of site -
A place without length, breadth, or height.
