Mom, Phineas and Ferb have a class where students learn how to build like them! Well Ferb, I know what we're gonna do today; in this class, we'll watch an episode of Phineas and Ferb together and then build the invention in the episode! We'll discuss the science behind Phineas and Ferb's invention and different design considerations to make the best project ever! One of our teachers is named Jeremy so you know we're legit. Wait, where's Perry?
