H to O

All about water.

It is the river source of every tear,
the rain and sleet within the vast atmosphere,
it's H to O,
good old H to O.
It goes with the flow, it is dear to the doe,
a moisture show.

The blue of ocean or the ice cap on Mars,
the condensation on some patio jars,
it's H to O,
elemental pro.
As far as I know it also hides in the snow,
a ball to throw.

A tray of water chillin’ doesn't think twice,
it stretches out a bit and then it is ice,
it seems to know,
hard on status quo.
And when it gets hot it rises right on the spot,
it's H to O.
