The best hook to grab the attention of 10 to 14-year-olds 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 is engaging because it relates to situations that the audience can easily identify with, suggesting that paper airplanes can enhance everyday experiences. It also piques curiosity about how something as simple as a piece of paper can create excitement.
