Toys, Games and Hobby Products Design Startracks Educational Learning Toy by Zhou Leijing Startracks is an educational board game about interstellar exploration, designed for children. The game teaches basic astronomy and physics through play. Rubidium magnets placed under the board simulate the gravitational pull of planets, so a small iron spaceship is drawn towards a planet when it lands. Players collect prop cards that carry astronomical facts and matching game skills. Two teams compete, and the first team to reach its goal wins. The board is made of synthetic wood and measures 500 millimetres in diameter.
