I am basically a fancy hat, with a much larger ego.

I hold four quarts, but not a drop of blood, I can measure milk, or petrol, or a flood. Eight whole pints are packed inside my frame, What standard unit goes by my name?

Paper fears me, rock does not.

I have a grooved face but I never frown, I spinningly dance as the needle drops down. I can hold a dark history or capture your voice, To scratch me or play me is entirely your choice. I am broken when athletes achieve something grand, Yet I safely spin music inside of your hand. What am I?

In lab I stand, clear and bright, I hold the liquids, day and night. Not a glass for you to drink, For science only, what do you think?
