Gravitrax C - Expansion Large

Kids are in for electrifying fun with the GraviTrax Power Extension! Electric stones send and receive signals, and as soon as a ball rolls through the trigger, a signal is triggered. Kids then determine whether the switch, the dome starter or the action stone lever should react to the signal. The electronic elevator brings balls up one level automatically and without manual reset. Thus, new energy is gained and an almost endless marble run adventure can start. This STEM system [Science, Technology, Engineering and Maths] is an ideal one to teach kids about gravity, magnetism, kinetic energy and fun. Hit a snag? Freestyle with your own track design or use the tasks and blueprints included to help you to get started in the world of GraviTrax! Are the gravity spheres stopping or flying off before reaching the end target? Time for some problem-solving. Rebuild and try something different!
