Look A Little Closer

Here's a little something
All of us can see each day
Now let's all take a look at it
Closer in every way
You'll see many things
That you'd never believe were there
So come and look a little closer
If you dare

Although there's so many tiny little parts
That your eyes can't see
You couldn't ever hope to guess
What it's gonna turn out to be
Is it round or flat, skinny, square
Or short or tall?
Close up it doesn't look like
What it is in any way at all

Did you guess what it is?
That's right!
