Blast Off T-shirt
Blast Off T-shirt cover painting by Bob for the Harry Harrison book
Blast Off: Science Fiction for Boys is a light-hearted adventure story centered on Jim, an imaginative and determined boy who dreams of traveling into space. Fascinated by rockets and science, Jim teams up with a friend to build a homemade spacecraft. Their project begins as a simple hobby but quickly grows into a daring, larger-than-life experiment fueled by curiosity, humor, and youthful optimism.
As the boys work on their rocket, they face mechanical mishaps, skeptical adults, and unexpected dangers. Through resourcefulness—and a good dose of luck—they learn real scientific principles while pushing the limits of what kids can accomplish. The story captures the excitement of early science fiction: the thrill of invention, the wonder of space exploration, and the belief that bold ideas can take you farther than you ever imagined.
