There's going to be a science fair at the school, and Leia can't wait to win the "Scientist of the Year" award for the project she's been working hard on. The problem is that you can't have Oswaldo and Tobias in the same workgroup. So she decides to help, giving them the classic "beans in cotton" so that she can focus only on her work: a perpetual motion machine. Oswaldo and Tobias manage to make fun of the entire event. They believe they are in a "science fiction fair" and not the normal, boring "Science Fair". Oswaldo Dresses up as a robot and duels with Tobias, who shoots imaginary lasers. They turn the fair into total chaos. It all ends with Leia's experiment being destroyed. She fights with her Oswaldo and Tobias but after seeing them downcast, she decides to fix things.
