The ZOOB 250 Moving Mind-Building Modeling System is a building set that's far different from the rest. With (250) pieces that come together in countless ways and creations that move after they're built, this ZOOB set provides endless opportunities for creativity and fun. What is ZOOB? ZOOB sets have (5) different styles of pieces that snap together in (20) ways to make connections that rotate, limbs that extend, axels that spin and much more. The pieces move after they're built together, so your child can create toys to play with instead of just looking at them. ZOOB's shape is inspired by nucleotides, the basic structure that makes up DNA. ZOOB captures the dynamic movement based on the way things move in nature instead of using traditional stacking connections. Encourages Kids to Use Their Imagination The best part about playing with ZOOB is exploring, discovering and using imagination to create any design that comes to mind. This gives ZOOB built-in educational value because children must use the most important tool of all for creation: their imaginations. The included instruction guides also teach children how to build (40) different creations for those who prefer to go by the book. Appeals to Both Boys and Girls Recommended for children 6-years to 10-years of age, this toy has appeal for both boys and girls. Some of the guided creations include bunnies, giraffes, kangaroos, dinosaurs, motorcycles, cell phones and much more.
