I am a loyal follower who never takes a step, yet I run in circles all day long. I am driven by stars you see on screen, or by the invisible current hidden in your walls. I can blow you away with my devotion, or slice through the heat without drawing blood. What am I?

I'm bendy and yellow, and ever so sweet. Sometimes if you split me, you can make a treat.

I can be putty in your hands, or hard as a rock. I come from the earth and can be green, stone, or even bone.

I stand on the podium, but never the peak, And a mantle of green is the fashion I seek. An era was named for my history and might, Though copper and tin had to fuse for my light.

You may use me to whip cream or knead dough, To stir batter or make marshmallows. You may attend me to find others in your field, Or to meet coworkers at your company. What am I?
