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

What is the largest organ in the human body? You might also talk about milk or bread dough developing one of these if left out in the open for a while. If you're easily offended people might say you need to grow a thicker one of these.

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?

I am a solitary figure, standing first of all to be, But add a letter to my front, and I shift instantly. Prepend a starting letter, and I’m vanished out of sight, Try a different head instead, for a wolf with no pack at night. With another guide I hold your ice cream, sculpted sweet, And with a final leader, I’m a chore that is complete. What's my name?
