ZOOB is the moving; mind building modelling system. Its pieces snap; click & pop together in twenty different ways to form joints that rotate; limbs that extend and axles that spin for unlimited; open-ended building. ZOOB allows kids (and adults) to learn; explore and create using their imaginations. And if they can imagine it; ZOOB can help animate it . . . from dinosaurs to DNA strands; from animals to aliens. ZOOBMobile Fastback H2H features two pull-back friction motors so kids can create their own ZOOBMobiles and race them against each other or they can also put the motors together to make a super vehicle that goes even faster; for up to forty feet. The Fastback H2H features 45 ZOOB pieces and eight high quality tyres that are notched so they work like gears. No batteries required.
