A Magnetic Attraction is the 17th episode in Season 3 of H2O: Just Add Water.


Cleo re-investigates the Mako rock when she's amazed to find it's become highly magnetic. Determined to unlock the mystery behind what is causing the water attacks Cleo shares her interest in the rock with Ryan Tate, a young geophysicist who works for Samantha in the National Parks Authority. Rikki doesn't respond well to Cleo consulting a stranger about Mako's secrets and a rift begins to develop between the girls. Ryan loans Cleo some equipment and she continues her experiments defying Rikki's warning and further straining the bond between them. She's stunned when Ryan confirms the rock's unusual properties appear to indicate it is identical with the rocks found on the moon. Rikki begins to spend more time alone in the Moon Pool and finds her powers have developed a surprising new ability in the cave. Bella and Cleo are shocked when they learn from Will the truth of what occurred with Rikki on the full moon, while Ryan is now very interested to learn more about the rock from Mako Island.


  • Cleo fighting with Rikki was like Emma and Rikki fighting in the previous two seasons.
  • Bella's behavior with the argument was like Cleo in the 1st and 2nd season. She didn't argue with them.
  • First appearance of Ryan Tate.




Ryan: You can use this to measure the magnetism of a rock.

Kim: (interrupts convo and holds out her rock) Measure the magnetism of my rock.
