Answer:
What goes in the water red, and comes out black?

They have not flesh, nor feathers, nor scales, nor bone. Yet they have fingers and thumbs of their own.
I am the tool, for inspiring many. Buy me in the store, for not much more than a penny. Don't overuse me, or my usefulness will go.

They are many and one, they wave and they drum, Used to cover a state, they go with you everywhere.
