Jake's desire to win the school science fair almost costs him his best friend. Jake Drake is excited about Despres Elementary School's first science fair. He wants to win the grand prize: a brand-new Hyper-Cross-Functional Bluntium Twelve computer system. And he really wants to beat the third-grade know-it-alls, Marsha McCall and Kevin Young. The trouble is, to beat the know-it-alls, Jake has to become a know-it-all himself. And he may just lose more than he wins.
