The best hook to grab the reader's attention would be: "Math class. The dinner table. Your little brother’s T-ball game. What if I told you that you could make all of these places much more exciting with a simple piece of paper?"
This hook effectively engages the 10 to 14-year-old audience by suggesting that they can enhance their everyday experiences with something as simple as a piece of paper. It's relatable and piques curiosity about the potential fun and creativity involved in making paper airplanes.
