The Engineering Lab Racing Car and Truck awaits you to build it and take you on exciting speed adventures! A scientific set to discover all the secrets of engineering in the most fun way! With this scientific lab, you can experiment with motion transmission systems by constructing 2 models. You will find 1 model to assemble according to the instruction manual or the APP and 1 model to assemble according to the APP. Experiment with over 130 elements to build a HOTROD with pull-back function. Try the APP using animated images and 3D models for step-by-step assembly. The App is compatible with ANDROIDTM, APPLE, and AMAZON. Made in Italy. The Learn and Create Build series promotes STEM (Science, Technology, Engineering, Mathematics) topics for the development and encouragement of children's knowledge in these areas. By conducting experiments, children improve their skills and are introduced to the world of science and technology. The Learn and Create series holds a leading position in the category of scientific toys, providing rich equipment, detailed information, and instructions for performing impressive and safe experiments and constructions, thus giving children the opportunity to get to know the sciences. It is an innovative series of toys with which children will have fun conducting experiments, using scientific tools, discovering physics, chemistry, astronomy, biology, botany, as well as major scientific and natural phenomena. The Learn and Create toys are the most creative, enjoyable, and safe way for children to learn the secrets of Science!
