I am on one now, and perhaps you are too, searching through riddles. Distance be damned; wherever signals may reach, feel free to call me.

I have a grid of ribs, but I have no spine. I breathe in the heat, but the chill is mine. I am always boiling under the hood, Keeping things cool like a good guard should. If I spring a leak, you’ll be stuck in the smoke, Because when I stop working, your engine’s a joke.

Dusty fingers dance on me, while chalk sings out its scratchy plea. I wear each lesson, line by line, till one soft wipe clears every line.

I'm a little bunny hiding under the sofa. I'm what they say we return to when all is said and done. Once I was so powerful a Bowl was named after me.

I make things hard when im hot, and dry when they're damp. To begin my job, I must first be fired.
