H2O: Just Add Water is an Australian live-action series for preteen-to-teenage girls that has been shown in North America on Nickelodeon and currently shows on Teen NICK as H2O. The story focuses on three friends who gain magical powers over water and after a trip to the mysterious Mako Island, turn into mermaids following "The Splash Method" (when they are wet they turn into mermaids, and when they are dry they aren't) after swimming in a magical pool during a full moon.The series was created by Jonathan M. Shiff. It is mostly about the girls' powers and dealing with them in real life. There were initially going to be only two seasons, but due to popular demand a third season was added, with several of the characters missing and a new girl, Bella, added to replace Emma. A spinoff series, Mako Mermaids An H 2 O Adventure, is available on Netflix.
