Answer:
Cold head and feet; round as a ball; always turning around myself.
Late afternoons I often bathe. I'll soak in water piping hot. My essence goes through. My see through clothes. Used up am I - I've gone to pot.
I am like thunder in your cranium
I have green hair a round red head and a long thin white beard.
I am useless when together but useful when I am broken apart. What am I?
What is always coming but never arrives?
