What is it?

Later in 2013 each child in Nifty Nine will have the chance to put something from home in the "What Is It?" bag.
At school they will need to describe this 'thing' to us and we will have to guess what it is.
Some of the questions we may ask could sound like this...
* What is it made of?
* What is it used for?
* Where would you find it?
* What does it smell like?

What questions would you ask...?
