I am an odd number. Take away one letter, and I become even. What number am I?

The more you take, the more you leave behind. What am I?

I am full of holes, yet I can hold water. What am I?

What has a head and a tail but no body?

What comes once in a minute, twice in a moment, but never in a thousand years?

What goes up but never comes down?

What has cities, but no houses; forests, but no trees; and rivers, but no water?

What has to be broken before you can use it?

I am always hungry, I must always be fed. The finger I touch will soon turn red.

I can fly without wings, cry without eyes, and see without a body. What am I?
