Eating contest emphasizes important economic principle

The game that we're about to do today is called swiss cake roll eating contest. Why does it relate it to economics ? Right, like, you just eat as fast as you can. Why is it economics? But you actually talk about diminishing return to utility. We tend to slow down as we do more and more of an item. Students will memorize the concept, but they don't really get to see it and they really experience it, even if it means watching somebody, they're experiencing it, sort of, live in the moment today. They have no idea what's going on. At the start of class, they'll see just some swiss cake roll boxes out on the table. In one box, there are 12 of them. They get 3 minutes to eat as many as they can. Not only the student that volunteers will get to experience that. Students will just sit in the back as an audience they will get to participate too. They have to pick who they think is going to win that competition. Students will get to go through this experience of, like, "Oh yeah, I can do this !" The first one, and they just, like, trouble like "Oh, this is so easy." The goal today is to actually watch the students start super excited as they're eating all these little swiss cake rolls, and then to see them actually slow down in the process of doing it. And that's what really diminishing returns is trying to highlight. I want students to be able to relate to whatever we did in class, to whatever they experience in their life.
