This video tutorial shows us how we can build our own electric car using one AA battery, pair of disc magnets and aluminum foil. It’s so simple that it only runs in a straight line, if you experiment with magnets you will see that it can take different directions. An ideal project to do with the little ones in the house. Its objective is simply fun and educational.
