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 option is engaging because it connects the concept of making a paper airplane to everyday situations that the audience can relate to, sparking curiosity about how such a simple activity could add excitement to their lives.
