Once upon a time, there was a little drop of water called Glug who lived in a river. Even though she didn’t know it, she had a very important mission on Earth, and that was in the cycle of water.

Glug was a very young water drop so she didn’t know why her mother would often leave the river and return a few days later. So one morning when the sun was shining brightly, Glug asked: “Mum, why do you leave the river sometimes?” Her mother answered: “Well, because we water drops have a very important job to do: we must ensure that the cycle of water continues.”

Glug was very surprised, for she had never imagined that her mother was so important to Earth. However, Glug wasn’t very sure exactly what this mission actually was, so she asked:

“So what’s the important mission, Mum?”

“It’s not just my mission, but yours too, and all the water drops on Earth.”

Glug was open-mouthed, for she too was part of this important mission for the planet.
