What is a Marble?

What is a marble? You might come to ask,

A sphere of pure glass, or does clay get a pass?

‍

What is the purpose of a marble? Depends on the day,

Why not ask its owner, and hear what they say?

Is it a toy made for games, in bright and sunny parks?

Or an art piece on display, to elicit smart remarks?

‍

What is a marble's size? Difficult to define,

How do you measure an item which comes in every waistline?

Can scientists synthesize molecular mibs in a lab?

Does Atlas roll a giant marble up an endless slab?

‍

What does a marble look like? Oh, do not ask me

How does one simply transcribe the rays of colors we all see?

Do they have to have colors, what about pure black or pure white?

Or the completely transparent, that still dance in the light?

‍

What is a marble? Depends on who answers,

But one thing is sure, they’re happiness enhancers!
