Josefa unplugged her laptop. She dragged the heavy box across the white desks. A stray pencil rolled under a chair. The room hummed quietly.
She poured baking soda into a plastic bottle. Vinegar waited in a beaker. Her tongue poked out. A drop splashed, sizzling on the desk.
The mixture erupted instantly! Purple foam shot up, sticking to her hair like sticky candy. She froze, holding gooey strands that dripped slowly.
She grabbed paper towels and scrubbed furiously. The stain spread to her sleeves and the floor. Jeans matched the disaster zone now.
A bubble popped near her elbow. Tiny smoke puffed out. She paused, wiping her hands on her stained jeans. The mess was huge.
She stepped back to admire the explosion. Picking up dried foam, it crumbled into glittery dust. Classroom lights reflected off the scattered residue.
Josefa smiled at the colorful chaos. It was an unexpected result. She already planned how to explain this messy, wonderful discovery.
The experiment was a success. Or maybe just a big mess. Either way, Josefa knew tomorrow would bring new ideas and more science.
