What Are Saturn's Rings Made Of? was a tri-fold science project made by Greg Heffley for the Science Fair in Hard Luck. The project is about the materials of Saturn's rings hence its title.
In an hurried attempt to avoid summer school, Greg worked on his project from the time he got home until 11:30 at night. Greg was proud of the final result as well as Susan Heffley but then realizes the project had to be typed out. Greg was extremely exhausted by that point and decided to set his alarm at 6 to finish the project however forgot to hit the snooze bar and thought he was screwed until he came downstairs only to find a fully typed project by Susan. He would turn it in the Science Fair during second period. [1]
