Scene 1 – The Dry Sand
Rain covered the garden in tiny sparkling drops.
Water dripped from the fence while puddles formed across the grass.
Milo stepped carefully around the mud.
Milo: “Everything is soaked.”
Nova suddenly stopped near the edge of the garden path.
Nova: “Wait.”
She pointed down at a small patch of sand beside the stones.
It looked completely dry.
Milo crouched immediately.
Milo: “That makes no sense.”
He touched the sand carefully.
Dry grains rolled between his fingers.
Milo: “How is this dry after all that rain?”
Dr. Zaptain stepped outside carrying a watering can.
He noticed the strange patch of sand and smiled slightly.
Dr. Zaptain: “Ah. I was wondering where I left that.”
