Once upon a time there was a dad and his two daughters.
"I have to go on a trip girls"
"But I have a gift for you."
"It's a glass marble, made from melted sand."
The girls loved to play with the marble.
One time they brought it to the beach.
"Uh oh. The marble is all sandy."
"I'll wash it", said Sage.
"Oh no!"
"What happened?", asked Mazie.
"I dropped the marble down the drain!"
"Don't worry Sage. We will find it together"
Mazie called their uncle.
"Uncle, where does the water go after it goes down the drain?"
"The water goes through pipes to the treatment plant. Maybe your marble went there."
So the girls walked to the treatment plant.
"Did you see a marble?"
"No, but our filter catches things like marbles, and a truck takes that to the landfill"
So the girls walked to the landfill.
"Did you see a marble?"
"No, but someone might have found it. Try posting a message to the Internet."
They got many messages.
But no one found their marble.
The girls were sad.
"Daddy gets homes tomorrow and is gonna be sad we lost the marble."
But then...
"I have an idea!" shouted Mazie.
The girls went back to the beach with their uncle.
He helped them make something.
The next day...
"DADDY! DADDY!"
Their dad was home.
They gave him a big hug.
"We lost the marble, but made a new one!"
And they showed it to him.
"Girls! I am so proud of you."
"This is the most magnificent marble I have ever seen."
"We love you daddy."
"I love you too girls".
