Kids Riddles

Question: I talk, but I do not speak my mind
I hear words, but I do not listen to thoughts
When I wake, all see me
When I sleep, all hear me
Many heads are on my shoulders
Many hands are at my feet
The strongest steel cannot break my visage
But the softest whisper can destroy me
The quietest whimper can be heard.

Question: I'll bring out your bulls,
and slow your roll.
I may even come out of your skull.

What am I?

Question: What is the easiest way to poke a balloon without popping it?

Question: what did the postman say to the mailbox?

Question: Draw, fire, or fill me;
I'm still empty.

What am I?
