Answer:
I have an eye, but I can't see. I usually have to work with something in my eye. What am I?
I have a small hill with seven holes.
I am filled with garb the price is free. Just return what you don't need.
Bright as diamonds, loud as thunder, never still, a thing of wonder. What am I?
I can wave my hands at you but I never say goodbye. You are always cool when with me even more so when I am high!
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
