2. What is made of water but if you put it into water it will die?
3. You can drop me from the tallest building and I'll be fine, but if you drop me in water I die. What am I?
4. I have no eyes, but cry and yet I have no wings, but fly. What am I?
5. Forward I am heavy, but backward I am not. What am I?
