Water parks are undebatably awesome. Alas, weather and location are two serious limitations when dealing with water-based activities. Fear not! We humans are quite resourceful and will never let things we cannot manipulate gone un-manipulated for long.

Intrepid engineers and visionaries-of-fun have given us the indoor water park, where the temperature never dips below 80, and where there's plenty of soaked concrete and the humid, stuffy atmosphere resounds with the sweet sounds of shrieking children reverberating off the steel-reinforced ceiling.

Suit up: these are the 15 craziest indoor water parks in the world.
