Answer:
When I am caught I am thrown away. When I escape you itch all day.
To you, rude would I never be, though I flag my tongue for all to see. What am I?
I shoot but never kills
I am higher than the king
I have cities with no people forests with no trees and oceans with no water.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
