Answer:
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. I have greatest power when given away yet lust for me keeps me locked away.
I'm really blue but when you see me I'm red. You don't see me too often. I'm there for you if you're hurt.
You write on me and secrets I can keep in places never seen. I spin like a top. Though stiff as a board, I'm often described like a mop. What am I?
I'm tall I'm round and hollow Seems to get chewed a bit But you'll rarely see me unless the other end is lit.
I am easy to waste and unstoppable
I go in hard, come out soft. Blow me hard and I'll make a pop. What am I?
