This supplementary kit contains key parts for exploring electricity and electromagnetism, and it needs to work with #1261 sience tour . Gigo patented electricity blocks are made easy and safe for connection and observation, which makes the magic of electricity even fetching and the interesting hands-on experiments feasible. Build your own circuits and observe how series and parallel connections generate different voltages and duration. See how electromagnet is made and learn natural examples or technology application with fun mechanism games.
