Bring Natalia’s story to life and dive deeper into hands-on electronics with this puzzle kit designed for curious minds. This continuation set picks up where the first act ends and unlocks new spintronic parts—transistors, an inductor, resistors, and a capacitor/voltmeter—so players can build more advanced mechanical circuits and explore 82 fresh puzzles that move from intermediate to advanced difficulty. Perfect for kids and adults who love problem-solving, logic challenges, and tactile STEM play, the kit includes a complete Act Two puzzle book and all parts needed to start solving right away. Compact, durable, and rewarding, it’s an engaging way to learn circuit behavior by watching and feeling how voltage and current move through real, physical mechanisms. Ages 8+.
