HANDS-ON BUILDING PROJECT FOR AGES 8+: Assemble a lightning-fast race car that's powered by nothing by air -- no batteries or electric motor required! SUPRISINGLY SPEEDY & REALISTIC! With just 12 pumps, the tank fills with air allowing the car to travel up to 13 feet per second (9 mph), reach distances of over 60 feet, and make engine noises as it zooms away! BUILT FOR LONG-LASTING PLAY: Durable building pieces are easy to assemble and designed to withstand multiple experiments, test drives, and races, guaranteeing hours of play and exploration. REAL-WORLD CONNECTIONS: Through assembly and experimentation, kids will learn about sustainable engineering design, clean technology, and essential physics concepts THOROUGH, EASY-TO-UNDERSTAND MANUAL: The 24-page, full-color manual guides assembly with step-by-step illustrated instructions and provides clear explanations of scientific concepts.
