The Water Cycle

“…every time you drink a glass of water, the odds are good that you will imbibe at least one molecule that passed through the bladder of Oliver Cromwell.  It’s just elementary probability theory”

Richard Dawkins, The God Delusion (2006)

Oliver Cromwell once drunk this stuff
then went and had a pee.
It trickled to a nearby stream
then meandered to the sea.
It evaporated to the clouds
which wandered far and free.
Not lonely, as Wordsworth said,
but quite companionably.

Orographic uplift is a phrase
to make a poet cry
so let’s skip the explanation
and watch the clouds float by.
But when they meet the distant hills
they’ll dump their load as rain.
And this collects in a reservoir
to become a drink again.

This cycle was repeated
in perpetuity
until we reach the modern age
where it was drunk by … me.
