An educational game having a number of parts where each part has a contact surface with first and second magnets movably joined to and interior face of the contact surface. A rod that defines a longitudinal axis parallel to the contact surface has the first magnet at one end and a second magnet at the opposite end, with the magnets having their polarity reversed to each other. An elongated housing encloses the rod on the interior face of the contact surface, and it moves the rod on the longitudinal axis along the housing.
