I speak without a mouth and hear with no ears. I have no body, but I come alive with wind. I disappear the moment you try to hold me? What am I?

I hold all kinds of liquid. Change my first to: M to pour liquid in, and drink from. R for a floor covering you don't want to spill on.

I sit and lie dormant prepared to burn. A knife in my gut, an explosion returned. Jam what is popped, my tail to the wall. Butter, jelly or cinnamon? Why not try them all?

I wear a sheepish grin, but my bark's a howl, for dinner plans, I cleverly prowl. What am I?

I have a heart that never beats, but I can make yours race. I can be asked a thousand times, yet I never speak a word of my own. The more you answer me, the more of me you might tend to create. What am I?
