The final command, in a line to the end. Stoked, it gains power And can be used to mend. A resourceful hawk species with a stick makes it friend. When spread, it’s a destructive and nutritional blend.

I’m a metal box with a fiery heart, I turn your breakfast into a work of art. I jump and I beep when my job is complete, what am I that makes your morning treat?

I live on your desk. Straight, black. Keep things together. Watch out for my bite.

I stand in your way or build what you need, A barrier or base, depending on deed. Kids stack me up high, then laugh as I fall, Or use me to build sturdy forts or a wall. When I visit writers, I tangle their words, Yet lay the foundations of cities and curbs.

In glass and mercury I lie, a slender line, I climb, descend, in Fahrenheit or Celsius I define.
