It's time for the annual science fair. This year, the kids at Rebus Elementary will be competing against the students of Piggot Academy. The prize is a trip to the American Museum of Natural History in New York! The members of the Abracadabra Club are dead-set on winning, but someone keeps sabotaging their projects. Who's to blame? That annoying Bug Jones? The snobby kids from Piggot? Someone is trying to make Rebus lose the competition -- and to find the culprit, the Abracadabra Club must reach deep into its bag of tricks!
