What would you do if you loved to surf, but lived nowhere near the ocean? Well, in Wales, a country in Great Britain, the world's first public artificial wave pool has been built. What was once an aluminum factory has been turned into the longest man-made surf wave in the world, using rainwater from a nearby reservoir to fill the lagoon. The pool is able to produce a 6ft-tall barrel of water that peels for 490 feet and runs for 16 seconds. So, living in a landlocked city doesn't have to keep people from enjoying the water. An artificial beach or lagoon could solve this problem, especially if they are built indoors.
