Experiment #256 - Hardcover

by Marty Kelley (Author), Marty Kelley (Illustrator)

Ian is wild about science experiments and for his latest (number 256) he's building a jet pack for his dog, Wilbur--the leftover parts shouldn't be anything to worry about, right? When Wilbur dons his new pack and blasts off, he leaves a swath of chaos in his wake and nobody is happy, Wilbur least of all. What's a budding inventor to do?
