Cata Z placed the heavy stone on the table. 'It’s a volcano!' she announced.
She poured red juice into the crack. Bubbles formed and popped with tiny hisses.
Cata Z giggled at the noisy fizz. She added more vinegar from a bottle.
A thick purple foam burst out, covering her nose. Her friends stared with wide eyes.
The foam spread across the entire table, trapping Cata Z’s hands.
She pulled harder, but the sticky goo held fast. The room filled with sweet-smelling bubbles.
Cata Z laughed as her friends helped scrape the foam away.
They all held up their messy, purple-stained fingers. The classroom smelled like grape soda.
