I am soft and cuddly that soothe your heart. But, If you pick my last name I am going to tear you all apart. Who am I?

I am taken from a mine and shut up in a wooden case, from which I am never released, and yet I am used by almost every person. What am I?

I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?

I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

A new Engineering building containing 100 offices had just been completed. John was hired to paint the numbers 1 to 100 on the doors. How many times will John have to paint the number nine (9)?

Give it food and it will live; give it water and it will die.

John enters a small room. The Door Closes.
When the door opens, John is in a larger room.

Explain?

A wooden log balances equally on the scales when weighed with three-quarters of a pound and three-quarters of a wooden log.

Can you calculate the weight of the entire wooden log?

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?

How can you write nineteen in a manner that if we take out one, it becomes twenty?
