A Sneeze and A Frozen Classroom

No one knew that Arlo’s sneeze could change the weather. But then again, no one had ever tested what happens when you mix ice mint gum, a helium balloon, and a leaky air conditioner. Arlo had done just that — in his lunch break “lab” under the staircase.
When the class returned after recess, there was frost on the blackboard. Chairs were icy. Miss Mehta’s coffee had turned into a coffee popsicle.
“Who turned on the North Pole setting?” someone joked.
Arlo stayed quiet. He hadn’t meant to invent Cold Blast Sneeze 2.0 — a sneeze so powerful, it brought the temperature down 15 degrees.
Later, when Principal Meera questioned everyone, Arlo confessed.
“Scientific curiosity,” he shrugged.
She blinked, sipped her thawing coffee, and whispered, “Next time, test in the backyard.”
