are planning to build a town called Atlantis City. It will be in the sea, about five miles away from the land. But

the most exciting idea comes from Japan. It is called Acropolis. Acropolis will be a huge sea city, with parks,

schools, a hospital and an airport…and it will move! It will travel slowly around the world. There are just two

problems. Acropolis will cost a lot of money to make. And for people who get seasick, it won't be much fun!
