Frank Einstein and the Antimatter Motor — Jon Scieszka

Frank Einstein (A) is a kid-genius scientist and inventor. Klink (B) is a self-assembled artificial-intelligence entity. And Klank (C) is a mostly self-assembled and artificial almost intelligence entity. Together they create an Antimatter Motor using the three states of matter: solid (D), liquid (El, and gas (F). Their plans to win the Midville Science Prize are all but guaranteed -- until Frank's classmate and archrival T Edison shows up!
