Poem: Why are bubbles round?

Bubbles are round because Mother Earth
And the moon are round,

Because the sea-tumbled grey and green pebbles
Are round, and the clock,

Compass, sextant, disk, L.E.D.,
And ring of fire, are round.

Bubbles are round because water molecules
Are attracted downward and inward,

Creating a fragile skin of surface tension
That cradles water like a baby.

Bubbles are round because tension
Draws the water into its most compact shape

And the most compact shape—
On this planet—is a ball.
