Every EarthBall comes with the 20 page Global Handbook, chock full of games, activities & resources for Earth adventurers of all ages. Also displays ‘NightGlow Cities’, allowing you to see the world’s cities glowing brightly at night. They are truly depicted as an astronaut would see Earth from space.
