To be a scientist is the ambition many children embrace while they are young. With sophisticated research and design, our Junior Inventor series of toys are capable of giving children as young as four the chance to interact with physical world. With well-crafted components, your little inventor will create a digger, a mechanical arm, a gravity vehicle, a crane, a rotating light, and much more. All tools and parts are designed for children's hands and skill levels and it’s great for developing children’s logical thinking and an understanding of Science, Technology, Engineering, Art and Mathematics (STEAM) principles. The completed experiments offer children great fun to operate and interact with friends – wave “hands” to say “hello”, drag a frog crossing between tables, or watch a moving picture through the zoetrope. How about inventing a never-tried gadget using your imagination? To help you start, Hape releases this "Know-how" APP with a finished sample display and detailed instructions teaching you how to build the experiments. Once your junior inventor become “senior”, they can always get full use of the components and tools to create wonders like a real inventor. Use the in-App sharing functions to upload your masterpieces in the GALLERY or post on social media. For safety reasons this product is not recommended for children under the age of three as it contains small components.
